We have been told that we're suppose to be getting a new HD dish starting next year.It's suppose to be as small as a triple sat ,and would aim at 99,101,103.Iam crossing my fingers hoping it's true.:)


Yes, they are on schedule to come in right after the DirecTV Media Center Tuner is released...Should be any minute now....hold it....hold it......

Ummm, think Telstar is referring to the Slimline-3 dish.

No actually i was referring to a different dish.No monopoles,1 5/8 mast,just like an 18x20.

as we have seen, an 18 X 20 will work for a 99, 101, 103 dish, I bet they just take the Phase III dish and stick a KA KU 3 lnb on it.
I am no longer connected with Directv or any other satellite provider

Sorry they're blurry. Note I messed with azimuth, elevation, and tilt for over an hour, and 2 different LNB manufacturers (which made a difference). The fine tuning bolts are very necessary. The end result were settings very close to recommended ka/ku settings for this area.

We got a Phase III dish with the Slimline 3 LNB to work, we are just worried about the rain fade issue. The dish is installed on the northern coast here in Cali, so a few more weeks we should see some good rains and find out what happens.

I have directv at my apartment in San Francisco just for Sunday Ticket. I have to open my window and swing around the dish every time I want to watch, so I basically have to pray for good weather on Sunday's or really bundle up to avoid freezing

Anyway, I was probably the only person disappointed that Sunday Ticket moved from Mpeg2 to Mpeg4 this year, because my window is not big enough for a slimline, so I have to stick with the 18X20.

Obviously I'm thrilled about the potential for making my 3lnb into a slimline. But I do have a few questions. I'm a bit concerned about getting a good signal on 99 and 103 b/c my 101 signal right now is only about 85-90. Also, you mentioned a difference in the LNB manufacturers...I just ordered one from Ebay...which one gave you better results? Also, I know I'm supposed to secure the LNB to the arm with self tapping screws...what size did people use? Finally...what are the tuning bolts that you talk about? Are you talking about the elevation and tilt on the back of the 3lnb?

Thanks for the help, and sorry for the stupid questions.

:righton:

Weather is always great in San Francisco.

Major props on the lengths you go to in order to get Sunday Ticket. I'd be doing the same thing in your situation. Hope the Slimline mod works out.

No problem.

Edit: New info on LNB attachment see post #48

Adjustment screws he is talking about are on the back of the AU9 and slimline 3 and are for fine tuning adjustments, yes it wound be nice to have on the phase3 dish as Ka signals are touchy but I got it working good in about 10-15 mins from scratch,just lightly tighten the adjustment stops till you get the signals correct then lock it down a bit tighter.:)

WNC AU9 heads work good/slimline 3 heads work good "confirmed". Any more information on this subject would be welcomed.

I think the LNB I used above with the white caps is the WNC. Also, I tried self tapping it and didn't like the results so I just used the holes on the triple sat arm, and the LNB hangs out about 1/2" but you can tighten the down with the nuts and it keeps the signal about the same.

With the high signal numbers you were able to get this is probably the best method to secure the LNB head,I did notice the alignment of the holes as the LNB is inserted about half way.

This just gets better every day. Thanks all!:)

This is great success guys! You just proved to Directv that they should fire all their engineers for wasting millions and use this forum for free advice.

On a serious note though I think they took into consideration the fact that 1) installers dont always peak right 2) installers dont mount dishes right 3) some areas have winds and rain. But in ideal conditions smaller dish obviously work as long as customer can peak it himself. Which is great. Next step is to try it with International dish it must work even better than triple sat.

The slimline and international are both 36". The international has a poor weight distribution, no fine tuning adjustables and does not work with standard mounts.

yes, this dish is a POS.

Yea, Ill put a Slimline up anyday over that pain in the butt 20 minute to assemble crap... But Im sure it would work just fine for the 99 and 103....

Sorry to hear this especially after you spent so much time making it work, Hope she is happy with SD (101 bird only).
-----------------------------------------------------------------------------------------------------------------------------------------------------

Question:So using the 5lnb I should still set the receiver for Slimline3 right?
-----------------------------------------------------------------------------------------------
Answer:

I've been testing the WNC 5LNB with the receiver set to Slimline 3 so far it works better, no 771 errors and the guide data always seems to download properly.

No missing channels or errors of any kind using 99-101-103 :)

The old mpeg2 HD channels in the 70s are just gone from the guide and the local SD channels from 119 just show up with a black screen,HD counterparts work great for east Tenn area.

The original 18" x 24" dish that received 101 & the spanish channels from 119, aka para todos dish, would be worth testing. Perhaps that was the dish the poster meant. Here is a photo of the type I'm referring to:

http://bestsyndicati...ct_tv_works.jpg

The larger surface area (when compared to the 18 x 20 phase III) would seem to be a plus, but the lnb arm mount looks to pose more of an issue for trying to mount the sl3 or sl5 lnb.

A Dish 500 or other Dish Network model might be worth trying as well.

Also am wondering: has anyone tried the Eagle Aspen (clear covers) 5 LNB with the phase III? Does the WNC LNB (white covers) work better on the phase III - is there a measurable difference?

I tried both, the WNC seemed to fit better and 'seemed' easier to tweak settings but overall worked the same.

How to build your own small HD dish for DirecTV:


LNB heads that work well when mounted to a phase 3 dish (18" X 20"),this is for 99 (HD),101 (SD),103 (HD) operation.

Slimline-3 LNB (SWM/SWiM versions OK) with receiver set to slimline 3. "Best all around operation :)"

WNC AU9 5 LNB (white caps) with receiver set to slimline 5. "Good operation but 771 errors for SD locals on 119 satellite and possible guide data issues "

Eagle Aspen (clear covers) 5 LNB with receiver set to slimline 5. "Good operation harder to mount LNB head also 771 errors for SD locals on 119 satellite and possible guide data issues "

Use slimline setup numbers to do course alignment of 101 signal, use 99(c/a/b) and 103(c/a/b) meter readings to fine tune and balance Ka band HD operation (The 14/16 transponders group for 99 and 103 is the key), signal numbers will range from the low 70s to the mid 90s for 99-101-103.

Adjust the tilt a little till 99 & 103 are balanced,Your going see low numbers on it initially probably in the 50s-60s then go back to the elevation adjustment and find the highest signal numbers for 103 & 99, signal numbers from the low 70s to the mid 80s are normal.

Use the normal screws/nuts in the pre drilled holes of the arm and LNB assembly, this alignment occurs when the LNB is inserted about half way.

The highest Ka signal numbers so far is when the LNB is fully inserted and flush in the arm tube,drilling new holes in the tube arm at the correct place and using the normal hardware to secure the LNB works well.

The key on the bottom of the LNB must pass to the inside of the dish arm tube,this can be done with a flat blade screw driver or metal nipper to make a notch for the key to fit into or the LNB key can be ground away with a grinder for a cleaner better fitting LNB.

FYI: I don't recommend the use of the 18" round or any round dish,you will end up with missing transponders.


Disclaimer : This dish is experimental and not supported by DirecTV.

Having said that we have many successful setups working out in the real world:)

Having worked on a KAKUKIT lnb downsizing a 1.2 meter to 1.0 meter dish I found the focal point to be an issue.
The lnb arm of the AU-9 dish is longer than the Phase III.
The beam of the 99 &103 may be too narrow on the phase III arm.
I'm going to "extend " the LNB arm on a phase III dish and see if I can get better signals on 99 & 103 simultaneously.
Was able to get 90's on 99 or 103 but not together.
Compromise was usually 60's to 80's.
All channels worked just want a little more margin!

OK...I got the LNB in the dish arm, and adjusted the elevation and tilt to the settings for the 5 LNB, but I was unable to get a signal on 101. I think this might be due to the narrow tolerances that I have b/c the window is pretty small. As it stands now, the dish is pointing pretty much straight out the window, but it is keying of 110. The 5 LNB keys off 101, so the dish needs to go to the right, and I think this might be where I am having problems. Here are the numbers for SF

3 LNB set-up

Elevation: 45.8
Azimuth: 145.9
Tilt: 105.1

5 LNB set-up

Elevation: 41
Tilt 115
Azimuth 132

As I mentioned before, my signals are only about 85 for 101 right now. Also, I'm not sure how far over 132 is from 146 (I don't have a compass). Do you guys thunk I need to move the dish foot in order to compensate for the different azimuth?

Here is a picture of the dish using the old 3 LNB
