View Full Version : 2" pole over 1 5/8" pole for Slimline
I already have a 1 5/8" pole for 3lnb. Getting the 5lnb. I've read of installers putting a 2" sleeve over the old pole. Is this considered OK? Is the 1 5/8 pole strong enough for the big dish? Or, should I get a new pole put in?

Hmm, better take a poll.

Used a 2" sleeve over my existing mount for my Slimline - works great!

IMHO... If they could have stuck with the 1 5/8" mount that a lot of already had... they would have.
As it would have made the "upgrades" significantly easier and quicker.
While it "may" work for some installations.
Unless you have a solid, reason not to use the 2" pole that is included with the dish...... I would go ahead and use it. I can understand where "maybe" you had a poll cemented into the ground or somewhere else...
But I would think in 90%+ of the cases... go with the 2" pole.

Can someone point me to where I could purchase one of those sleeves? I've got a smaller pole in the yard to which I'd like to transfer a dish.

Put it over the pole, instead of using the slot.
I have my 5 foot 1 5/8 pole cemented in the ground and there is only 18 inches above ground level. Its very solid so the installer put a sleeve over it and ran some self tapping screws though the sleeve and into the existing pole and it works very well.
If the installer needed to put a new pole in the ground for my 5 LNB dish would he have cemented it in or what is the proper protocol they use for doing it ?
Steve Robertson
02-15-07, 04:45 AM
I am in the same boat and was thinking of something like this as opposed to having to put in another pole, I will give this some thought.
My pole is about 5ft high and about 2-3 ft into the ground in a big block of cement so do you think this would still be an option to try?

It should be cemented, that is the proper way.
Brings back a memory...
My neighbor ordered a directv system from Circuit City and I was outside watching the installer doing the pole install.
He did not have a hole digger on his truck, so, he dug a 2' hole in the ground placed the pole inside, leveled it and then packed the dirt around it.
This was for the 3 lnb install done 2 years ago.
I kid you not. I could not believe what I was seeing.

thats almost ridiculous.....actually, it is ridiculous ....hehe....so the installers carry bags of ready set cement with them on jobs ? My pole has been in the ground for 12 or 13 years and isnt even rusty but I wonder if I should have had him install a new one anyway....

If you have a very strong cemented 1-5/8" pole in the ground, the best solution is to get a 2 inch aluminized piece of tailpipe from the muffler and a bag of "cement grout" from Home Depot or Lowes.
Dig down around the pole to the concrete. You will need a good post level to get the new pole plumb. Fit the tailpipe over the current pipe. Mix and fill the space between the poles as well as into the center of the original pipe.
You will have a very very strong pole that will last for years. Just make sure that you use the stuff specifically labeled as high strength cement grout.

The same cement grout method could easily be used with placing a sleeve on a standard "J" pole mount. They make a black rubber/vinyl drainage pipe pluming adapter with stainless hose clamps with one end for 1-1/4" nominal pipe and the other for 1-1/2 nominal pipe. This could be attached to the bottom of a two inch sleeve. Plug the bottom of the original pole below the sleeve with a wadded plastic bag. Fill the spaces with the grout, while maintaining plumb.
I'd only recommend this if there is time for the cement grout to harden. Just be sure that the 2" sleeve is long enough to fit the dish mount sleeve at the top and that there is enough length at the bottom to fit two monopole braces.
If I was to do this often, as an installer, I'd look into fast set cement grout or some other stuff like a fast setting epoxy.

Steve,
Just curious, why did the tech at Solid Signal discourage the use of the pipe adapter?
I installed mine over an existing 1-5/8" cemented ground mount and it has been rock solid with the 5 lnb Slimline. Been in place over a month and already been through 30-40 mph sustained winds without a problem.
Beats the heck out of installing a new ground mount!

Chuck,
How high off the ground are you I am about 5ft and the tech said that wind would be a problem. I may give this a shot seeing as it works for you but I may call the install company and see what they have to say about it. To me this is the perfect solution.
ChuckBoozer
02-16-07, 09:49 AM
My pole is slightly shorter than your set-up - approx. 4 - 4 1/2 feet high.
PS - I went ahead and ordered the sleeve prior to my installation date. When the tech arrived, I helped him set-up the Slimline over the mount and made sure I was comfortable with the set-up.
It may not be the right solution for everyone, but I am pleased with the results.
To put a quick pipe adapter is fine and is considered 'a-ok' for DBS installs. Also to self tap a pole over a 1 5/8" pipe is also allowed. Everything has to be plumb.

Thanks for the replys I am going to give this a shot as right I already have two poles and really don't want a 3rd one. I will be there with the tech as well to make sure I am comfortable with the setup. Worst case I just have to put another pole in but this is so much easier

The best way to fix the 1 5/8" pole that is mounted into the ground is to use a pice of 1 1/2 " ID 2" OD pvc pipe and cut it to the length of the pole. Then you will want to cut it down the middle from top to bottom. Then you will slide that pvc pipe down over that 1 5/8 " pole and when you put that new 5 lnb dish on that pipe it fits like a glove. then just tighten it down and you are set to go. Also you will want to drill a hole thru the pipe and put a nut and bolt so the pvc pipe can't ever move..And this really does work very well and is very solid..Hope this helps you out :)

That is a interesting way of doing it. I think if this adapter I bought doesn't work I will just put another pole in and cut the old one down. They are actually located at the far backend of my yard so it is not like they stick out like a sore thumb.

It will work really well for you because that is the way we have to install them when we are replace the old dish with the new 5lnb dish. it is a very good way to fix the pole size for the customers. the pole is strong enough to hold that dish but the size is to small in OD. So you and do it and it will work for you or anyone else just fine.. good luck in whatever you do..have a good day! :)

Here is aphoto of an adapter that I just manufactured in small quantity. It is made from a section of 1-1/2 inch nominal flexible polyethylene pipe. It is a force fit, but needs a couple of self drilling screws to hold it in place and to keep it from sliding down the pole. There is enough space for attaching two monopoles, which is highly recommended. Two are not installed. One has been installed, but not completely in place. The two is a piece of 2 inch actual diameter tailpipe with 16 gauge or .065" walls. The grey pole is a standard 1-5/8 DirecTV/Dish "J" pole.

I have watched how much the dish blows around on the bigger OEM Mast. The smaller mast would be even worse.
As the H20/HR20s record one reading of the Ka transponders, you really don't know exactly what they are doing - especially if you havent gotten beside one in a good 15-20 mph wind.

I really like this box and if it runs the way it is supposed to I will like it better than TIVO there is aome really cool things on this box and the speed is so much better than TIVO. I guess the onlt negative is that it seems to take a while to change channels and sometimes when I go to change channels I have to do it twce. I think the PQ is much better as well.

With regards to the slowness of changing channels, there are a number of threads that discuss setting TV resolutions and other settings. I myself prefer to go with Native off and set my HR20 to only recognize 720P (what my TV supports) - it speeds up channel changing considerably and I am happy with the picture quality.

I'm not sure if I want the 5lnb dish mounted on the roof, I might have a tree problem. I was thinking about planting a pole beside the house that would extend above the gutter and secure it to the house somehow just below the eve. I t would be about 10 to 12 feet tall. My questions are:
1. Is there a problem with a roof mount?
2. What kind of pole would I use that is about 15 feet long?
3. How many cables need to run to the distribution center for cable?

In reverse order
3) 4 Cables to the distribution center should serve you well - though I'd run an extra 1 or 2 for good measure. With 4 and a WB68 multiswitch, you could home run up to 8 connections to the distribution center - and 16 with a WB616 - thus 4 cables will serve you well to your distribution center.
2) Schedule 80 - but you will have to make sure that is firmly secured in the ground - and also need to secure it to the house as you note. Otherwise, I would never recommend that route.
1) The potential with roof mounts are water leaks. That's true no matter what you do on the roof if you drill a hole (or install a skylight) on the roof. You can find as many different opinions on roof mounting as there are opinions on anything else - it will just depend on a number of factors - and one size does not fit all in that department.

2) Schedule 80 - but you will have to make sure that is firmly secured in the ground - and also need to secure it to the house as you note. Otherwise, I would never recommend that route.
Schedule 80 pipe is not necessary and overly heavy, unless you use aluminum.
As one, who is experienced in mechanical and structual engineering, I would have to say that the pole need to ne no stonger than 14 or even 16 gauge steel, unless the portion extending above the fastening point is longer than 3 feet. That fastening point us where the hold needs to be the strongest, The lower portion need not to be even fastened into the ground at all, since it mainly bears the weight of the entire assembly. It will not be subject to high lateral forces, as it will be at the end of a long lever arm. That end can be set on a small patio paving stone or even a piece of pressure treated 2x6 rated for ground contact.
An ander eave mount would be a better option, if a roof mount is out of the question.

a 2 in sleeve over a 1 5/8 pole is still a 1 5/8 support. If the 1 5/8 pole is connected to the mount, that's what you get. Granted it might be a bit stronger than a 1 5/8 by itself, don't skimp here. Get the 2 in - you won't be sorry.

The AU9 Slimline dish weighs almost 25 pounds and is approximately 5 square feet in size. With that weight and wind load potential on the end of whatever mount you use, you are asking for trouble if you install it on anything less than the full 2 inch diameter steel pole that it is designed to mount on. Even with that mounting size, it should be braced with at least one monopole to ensure stability. Don't forget that a shift in position of 1 degree or less may seriously affect your signal quality. Cheap or lazy is not the way to go. :nono:

Not really! It is a matter of cost..........
When the original DirecTV dishes were first manufactured, 1.67" tubing became the standard for the mount, because it was a common US industry standard for 1-1/4 inch nominal pipe. The next larger size was 2.37," which is the standard outer diameter for 2 inch nominal pipe. At that time, Channel Master, Winegard and KTI were all US manufacturers. That's why standard US chain link fence posts are 1.67 inches in diameter. US tube manufacturing equipment dies are set up for the particular diameter.
Fast forward to the current industry; Almost all AU9 dishes are NOW made in China or Taiwan. Their tubing manufacturing equipment is standardized a5 50 millimeters, which works out to the 2 inch equivalent. Basically, there is more equipment overseas to manufacture tubing in 50 milimeters.
Winegard still manufactures a 75 CM (32 inch) dish that mounts on a standard 1-5/8' actual tube mount. They have been doing so for over 10 years. There are many installed units and many have survived winds of over 100 mph.
So, if they were really concerned with strength, they would have gone to 2.37 inches in diameter. That was the old DirecWay and Primestar standard. If strength was DirecTV' real concern, they would have gone to that pole diameter.
Dish Network made SuperDishes with 2.37 and 2 inch pole diameters. The 2.37 inch poles were made in USA by Channel Master. The 2.0" poles were made in Asia.
A standard 1-5/8 mount is shorter and sits lower. If fastened and braced correctly, it can easily handle the extra load of a slimline dish.

http://i19.tinypic.com/2hf1282.jpg
From my experience as an engineer, I'd have to say that, on account that the install uses the standard DirecTV supplied parts, the dish is positioned higher above the roof than really necessary. For the sake of strength and steadiness of the nount, 12-18 inches above the roof for the bottom of the dish would have been optimum. To be fair to the installer, the mounting parts supplied with the dish are designed for a multitude of mounting situations, including the swing or azmuth of the dish and the pitch of the roof. There is an exponetial increase in movement from wind load as the length of the lever arm increases. So, in the particular situation shown by the poster, an older 1-5/8" pole adapted to two inches might be fine. Using a 1-5/8" pole would substantially decrease the length of the lever arm and loading.
If I were doing the particular installation, I would have positioned the dish and the monopoles in a way that the mounting pole and the monopoles would have formed an outline as close to a regular tetrahedron as possible. In a regular or perfect tetrahedron, each of the edges would be of equal length. This would probably be be strongest structual shape when place on either a static or dynamic load.

I have a 1 5/8' old metal fence post cemented in the ground (had my Phase 3 dish on it). Now with the 2" adapter the AT9 is solid as a rock (it obviously has no mounting arms being on a fence post). Been thru 3 major wind storms and a blizzard since I got that adapter and the dish hasn't moved at all. All it really takes is for it to be properly tightened down (which many installers don't do) and it's not gonna move.
From my experience as an engineer, I'd have to say that, on account that the install uses the standard DirecTV supplied parts, the dish is positioned higher above the roof than really necessary. For the sake of strength and steadiness of the nount, 12-18 inches above the roof for the bottom of the dish would have been optimum. To be fair to the installer, the mounting parts supplied with the dish are designed for a multitude of mounting situations, including the swing or azmuth of the dish and the pitch of the roof. There is an exponetial increase in movement from wind load as the length of the lever arm increases. So, in the particular situation shown by the poster, an older 1-5/8" pole adapted to two inches might be fine. Using a 1-5/8" pole would substantially decrease the length of the lever arm and loading.
If I were doing the particular installation, I would have positioned the dish and the monopoles in a way that the mounting pole and the monopoles would have formed an outline as close to a regular tetrahedron as possible. In a regular or perfect tetrahedron, each of the edges would be of equal length. This would probably be be strongest structual shape when place on either a static or dynamic load.I find it interesting that since I expressed an opinion questioning the adequacy of using a 1 5/8 pole to mount an antenna which is designed for a heavier mount, you find it necessary to criticize how my antenna is mounted. (By the way, it was mounted by an installer using the parts that came with it and not some kludged-up compromise of hardware store parts.)
Your statement of how you would mount my antenna based on "your experience as an engineer" makes not a whit of difference to me (I am a retired professional civil engineer myself), since all I care about is that the antenna is stable and I get signal strengths above 95 which do not fluctuate.

Obviously, this poster has NEVER, himself, installed and serviced satellite TV systems.
The next larger size was 2.37," which is the standard outer diameter for 2 inch nominal pipe.Do they not have 1-1/2" pipe where you come from? It is very near 2" OD (1.90" before plating) and available wall thicknesses up to 0.4".

Yeah. I need to clarify my post. I meant that 2 in nominal was the next step up for satellitr dishes.
About 6 years ago, I got some VSAT dishes that used a two inch actual Made in USA mast. I tried to use 1-1/2 nominal pipe of the dimension you mentioned. I had nothing but problems. The clamp never fastened correctly without a custom sleeve. So, from 25 years of experience in the satellite industry, I saw just a few mounts using a 2 inch actual mast, until the AT9.

Where can you get the monpoles everyone is referring too? I guess you could get a tripod kit meant for a pole...something like solid signal website : prod_display.asp?PROD=PVTP2 ... but not really what I want (and yes, the size is wrong - just good pict for example). If anyone has a better place to get something better, I'd like to know!

Clearly you have never been up at the dish during your supposed storms.
I HAVE a AT9 on the proper mount - at first without additional bracing. After watching it during 20-25mph wind gusts, its clear why D* wants a monopole brace on it.
Your statements are absolutely false.
Even a 2" mount by itself isn't enough to keep these dishes from shaking in the wind - anything smaller is comical.

With all due respect, I have been using the 2" adapter for my Slimline ground mount for over three months. It has been through a number of wind storms, including 50mph + gusts last week. It is rock solid - my signal strengths are always consistently in the mid-high 90's.
I can't speak for roof mount installations, but an adapter works great for solid ground mount installs.

As I said before, and, at the risk of sounding like a broken record, It's the length of the LEVER ARM that counts. I see that your pole is not much more that 3-4 feet out of the ground. A large diameter pole is only necessary for a long pole. The same could be said of a pole braced with monopoles. For any one foot increase in height, wind pressure forces are multiplied by the square of the total length. So, keeping it short is the key. A 1-5/8 original pole is about 1/3 shorter. So, it'll receive about half of the deflection pressure of the longer one supplied with the AU9 dish.

Again, you know not what you speak of.
You cannot monitor the Ka transponders in real time so you have no idea what is going on at the dish or with your Ka signals. The newer STBs do not allow you to monitor the Ka transponders except for a one time snapshot.
Just because you can get a 90+ in the Ku band means nothing on the narrower Ka band where all HD will be shortly, especially as the dish is wobbling all over the place.

you can put the 2"pole over the basic pole and use self tappers to hold it down and it is directv approved just as long as the original pole is cemented with 100 pounds of concrete which is usually not on a 1 5/8 pole since with the basic pole directv only requires us to use 50 lbs concrete with the basic pole and 100 lbs. with the 2" kaku pole. so to answer the question no do not sleeve the 1 5/8 pole just get a new pole.

It's not the amount or size of the mass of concrete, it's how it's placed. Very little or none is needed at the bottom or the end of the lever arm in the ground. The point, where the pole comes out of the ground or fulcrum, depending on the soil conditions, is where most of teh mass and surface area needs to be concentrated for the sturdiest mount. Here, in Upstate South Carolina, with it heavy red clay soil, as little as 20 pounds of concrete, placed strategically, provides for a sufficient mounting. In loose "gumbo" soil as found in Houston, Texas, 80 pounds may be necessary.
The newer STBs do not allow you to monitor the Ka transponders except for a one time snapshot.
Are you sure about this? My HR20 shows signal meters for the Ka's, and they appear to be working, although I have not tried adjusting the dish while watching them.
Also, I believe some of the high end signal meters are also capable of monitoring Ka.

Excuse me but you don't know about my setup or my conditions.
I had lots of problems with wind on this pole because I had a makeshift homemade adapter that just wasn't right. The dish would spin during even moderate winds.
Got the 2" adapter and no troubles at all since.
And yes, the pole and dish are right outside my 4-season porch and I made it a point to watch the dish during a couple wind storms with 35-40 mph steady winds with gusts well over 50 mph to see the performance.
I even went outside during such storms and stood next to the dish to watch it. Minor pole wobble can be barely seen during the highest wind guests which were enough to make it hard for me to stand
The dish does not move.
Period.
Signals are never lost.
Period.
Recordings have no issues during such storms. Watched an entire 3 hour hockey game and a 2 hour movie afterwords during the last blizzard. Heavy blinding snow and steady 35 mph winds, gusts over 50.
No problems now that I have a proper 2" mount on the pole.
So please, don't speak for me or how things works in my setup when you just don't know.
At least in my situation it's a heavy steel fence pole about 4 feet high buried in cement into the ground at least a foot.
Besides the fact that these types of bad wind storms only happen a couple times each spring and fall. Only other times will be during the initial down gusts at the front of a thunderstorm that only lasts perhaps a minute.
Basically, no issues and all works perfectly.

Anyone who has watched the signals on earlier meters know they vary. The H20 series of IRDs takes a one shot picture.

Nope. If you read carefully on things such as the new Super Buddy that claims Ka compatiability, its the same method to tune as D* uses with the other meters - adjusting off 101W Ku.

All I can say is BS - I've seen how these things wiggle in the breeze and so has D*, which is why they use monopoles even on their 2" mountings - which is why you should not use an adapter.
If you could use a simple adapter, don't you think D* would have taken the cheap way out instead of having installers drill more holes? :eek2:
Think about it for about 2 seconds.

I agree I have used this adapter for 2 months now with winds hitting 50 mph with no problem whatsoever so I am happy I went this route.

I'm still confused why it is desired to use a 2" pole OVER a 1 5/8 pole instead of a 2' pole from the get-go. I would use something even thicker if it were possible. Over-kill never hurt anyone! Unless you are saying the 2 " pole fits snugly over the 1 5/8"? That would be the equivalent of a think walled pipe?
Keep in mind most of the "movement" would come from the bolts connecting the dish to the pole and/or the bolts used to connect the pole to the base. Like a chain, the weakest link is the problem.
Anyone who has watched the signals on earlier meters know they vary. The H20 series of IRDs takes a one shot picture.
Sorry, but my HR20 signal meters absolutely do slow a live stream and vary while monitoring 99 and 103 transponders.
Nope. If you read carefully on things such as the new Super Buddy that claims Ka compatiability, its the same method to tune as D* uses with the other meters - adjusting off 101W Ku.
I did not say anything about the correct procedure to align a 5-LNB, I said there were meters that were capable of reading Ka, and that fact is true, there are meters that are capable of reading Ka.

Whatever then. Had high winds again yesterday. About 45 mph when I got home. I watched the dish and it barely wobbles in the highest guests. IT IS SOLID. Not sure what other way I can say that. Heck, the other 3 poles that were on this old fence line, I needed a pickup tied to the poles to get them bent enough to snap them off. My father-in-law and myself could not get them to move with just our weight and strength (much more then a wind gust).
So maybe I just have some super poles or something. Heck, they were there when we bought the house a decade ago. Took 3 down and left one up for the dish. Other poles may not be so sturdy. Great. So what is so hard about accepting that it's working for me? I don't know why you care so much.
So whatever on your BS. You have no idea how my pole is setup. Get off your high horse that you are right and people's installs don't work when in fact they do.

It's not desired. It's already there. Mine is an old metal fence post buried in cement into the ground which has held all my older dishes. So why not try it? If it doesn't work then I can dig it up and replace it so for little expense I try it and it works fine. Saves me killing my back or hiring someone to do it.
And check the adapter in the links. It fits pretty snug over the 1 5/8 inch pole and has bolds that you screw into the pole it's going over to make it nice and tight.
I'll try to take some pics when I get home and post them.

Different strokes for different folks, but here's the bottom line for me - the 2" adapter works great and is extremely snug and stable. My dish does not move, period.
And I will echo what I said earlier, I get very solid signal strengths (mid-high 90's)across all available transponders (including the KA band on 99 & 103).
Why should I bury another pole in the ground when this solution works great?
JFHughes08088
04-24-07, 04:15 PM
Ah, If you have a 1 5/8 pole cemented into the ground, that would make sense. Why bust it up, replace, etc. Hey, if 1 5/8 with a sleeve keeps the dish in place, that willd work. I though you were talking about a roof mount. Good luck. Signal strength in the 90's is as good a picture as you r gonna get. I'm told anything above the 70's in undistinguishable. They tell me there is no picture difference between a reading of 80 and 97. Me, I'm in the high 90's but it probably doesn't get me a better picture. (although I will admit it is something of a competition sport - higher number = better...............)

Like bonscott87 said, the older dishes used the 1 5/8 pole and foot in some cases. To avoid re-setting or re-drilling, the debate is whether or not to use the old setup or do the work to use a 2" pipe. I had to use the 2", a hurricane down here would twist a 1 5/8 right off the house, monopoles or not.
bonscott87
04-24-07, 08:37 PM
And I would suggest that if it's a roof mount or using the mount that comes with an older dish then definitely replace the 1 5/8th with the 2" mount that comes with the 5 LNB if at all possible. Stability is much more an issue in that situation.
A pole cemented into the ground, not so much of an issue. :D

Got one of those too for my FTA dish set-up - 2 3/8" of solid pipe!
Is there any thing special about the pole? can I just put a 2-inch pipe in a bucket of concrete? and is there a special installation fee for a pole mount? This is an apt, so I cant leave holes in the place.
Also, do they provide a piece of flat coax to go under the patio door?
also, the guy at Bestbuy told me that I should use a piece of 4x4 lumber and not a pipe...that sounds wrong, is it?

Wood can warp, crack and sag, and change the dish position. Better to go with a metal pipe.

My installer just sledge on a driving sleeve drove my 2" pole into the ground a good 3 ft. My sat is SOLID, but I may at some point go back and concrete it in with a a large conduit fitting for the cables. In wind it's protected by the nearby fence line, and the house, as it sits in between my house and the fence with 3 feet on the left and 10 feet on the right, but there's no direct line of site wind.
The ground where I live is solid clay gumbo so it doesn't move much.
However, I may cement it in later for 'good measure'. I'm just still leaving it as it is in case DTV service goes to the porta potty as I have Verizon FiOS service for internet, and everything setup so if DTV messes around with me I just call up Verizon, have a tech plug in the new boxes, pull the 6x8 in my tech wiring closet and plug all the coax back into the 3GZ splitter, and go on my happy way. I have dedicated runs to the FiOS box (dual Cat 6, and dual RG6 quad) as well as the 4 quad RG6 coming in from the pole to my tech wiring closet.
I wouldn't let them touch my roof with a ten foot pole as it's a brand new house with the roof warranty still in tact and it's brick on all sides, so I didn't want them 'accidentally' ripping a hole in the grout / brick with their anchors.
