QUAD LBNFS!!!!!! WHERE ARE THEY?!?!?!?!?!?

[jeffwtux]

Are any other Dish Network retailers having a hard time getting Quad LNBFs???? Echosphere tells me that they haven't had them since last Thursday and won't for 2-3 weeks. They tell me I should have enough inventory for 4 weeks. It's completely unreasonable for them to expect us be able to afford to carry 3-4 weeks of quad inventory. They have far more money than I do.

Well that's why they have more money. :rolleyes:

What exactly are the quad LNBF's for again?

[Mark Lamutt]

Quad are "just like the twins" except they have 4 lines coming out that either go directly to your receivers or can be cascaded with sw21s for 61.5 or 148. Basically, the quad is 2 dual lnbs with a built in sw44 switch. (Way oversimplified, but you get the idea.)

[jeffwtux]

Yeah, Mark has it right. The problem is that they don't have any. I might lose 3 sales because of this. Would you buy from a guy if had to delay your install one week because he couldn't get a stupid part??? I don't think I would buy from myself.

[Lightnin1]

I was told my rep that there trying to use all the duals up because if the merger goes through, they will be junk when the new 3-satellite dish comes out. They are trying to keep all the twins and quads because they can be modified to work with this dish. The duals can't.:ewww:

[Jacob S]

Well what is the point in trying to use the duals if they are just going to have to go back and replace them later on? That defeats the purpose of using the duals in the first place. This is just like admitting that what they are using now wont work with the new dish. Pointless and more fuss, work, and trouble it seems like to me.

Mark, somewhere I read that Dish is not even recommending the Quad with the SW21's any more. That they were supposed to be using the Quad with the SW 64 now.

[Neil Derryberry]

I can't imagine why you would use a quad with an sw64... In fact, I doubt that you could. The only valid lnb with a sw64 is a dual, AFAIK.

Dish has always had hardware shortage issues on most of it`s inventory on a regular basis. The small operation dealer that wants to "buy inventory as they sell" have been hurt time and time again.

We use to stock over $100,000 of equipment between Dish/DTV and were able to avoid that problem most of the time, although due to the high volume we bought our salesman did shun small retailers on many occasions.

I guess when they are sending one pallets of product at a time .. one does get special treatment ;)

The Quad LNB is similar to the Twin, except that it has four outputs for up to 4 receivers. With SW21 switches, the Quad will support 61.5 or 145 on up to two of the receivers (the DISH 300 LNB only has two outputs). The Quad may also be configured as follows: With an SW64 switch, the Quad will support up to four receivers on 119, 110, and either 61.5 or 145. With two SW64 switches and 6 high frequency splitters, the Quad will support up to 8 receivers on 119, 110, and 61.5 or 145.

Remember: You can still hook up to 2 receivers to the DISH 500 without needing the Quad LNB. In simple terms, the Quad LNB is only necessary when more than 2 receivers will be installed.

I just purchased a quad from dishdepot last nigh. It's on a UPS truck now. They even have a rebate of $35 for sending back the LNBs and SW21s you replace.

[John Corn]

I purchased a Quad LNB for Dish Depot today, as long as Randy didn't buy the last one they have. :D
I'm getting ready for the 721, I'm getting nervous, I hope it's not a flop.

And for the life of me, why they didn't show us the bells and whistles of the 721 last night on the Charlie Chat is beyond me...........grrrrrrrrrrr:mad:

[Swampthing]

Hmmm... I guess I didn't realize the Quad 500s are so rare! This afternoon when a Dish tech came out to fix a busted SW42 switch, I asked if I could upgrade to a Quad and he said he had a brand new one sitting in his van. Had the baby installed, and now I've got four receivers hooked up to one satellite dish... :)

It sounds like you are doing what I want to do. I currently have two receivers with a twin lnb, and I want to replace one of them with the 721. I was told that all I need is a quad lnb OR an SW64. Is that accurate? Just want to make sure before I buy it. TIA

[John Corn]

Hi cfogus, the cheapest way out is the Quad, you can sell your Twin or Dish Depot will give you $50.00 trade in.

If you use an SW64 you would have to buy a Dual LNB.
Someone with a Twin LNB it's much cheaper to buy just the Quad instead of having to buy a Dual Lnb and an SW 64.

If you just using a Dish 500 and don't need 61.5 or 148 you can get buy using two duals, two multi switches, and as many SW21 as you have receivers. Multiswitches are pretty cheap. You take both outputs from the 119 Lnbf and run it into a multi. Do the same for 110 and then put the SW21 in line.

I am not sharing! :D Hopefully you have your shipping notice by now. The rebate deal makes this a pretty sweet price for the quad. My plan is to bring my second DP back on line along my original DP and our 501 and wait until I hear the grist on the 721.

[John Corn]

Yep, Randy mine has shipped as well. :righton:

[Randy_B]

Climbed the 30' extension ladder and installed my quad yesterday. The quad is noticeably heavier than two duals so I am a bit concerned about having to use the same plastic shroud to connect it to the mounting arm. Seemed a bit weak with just the small bolt holding it to the arm, so I wrapped the shroud with some electrical tape (at the neck and the top) to help give a little more strength.

[DRJDAN]

My Quad LNBF went out. Dish Service replaced it with two Dual LNBF, SW44 switch, power Inserter and power supply. The installer said could not get the Quad replacement. He said this will work just fine. Any technical advantage of one set up or the other. I have 4 receivers.

[scooper]

Major advantage of the QUAD would be ease of cabling (4 lines, directly from QUAD to receiver). The SW44 setup might have an advantage if you have long runs and place the SW44 about half way between. But as long as all receivers have been properly setup, operationally, it should be a wash.

[DRJDAN]

Where does the Quad get it's power since it has no inserter? What signal strength should I have as a minimun?

You seem to be missing the point. The reason they will do this is so they have an excuse later to charge you to come back out and upgrade you dish. Make sense? It does to me anyway because I know how dish works.

The quad gets the usual 18+volts off of the receiver. You should have the same signal strength as a twin. I like to see at least 100 on both birds. Nothing under 90. If you are over 75ft in distance from each input to the receiver, in-line amps(950-2150 Mhz) are required for reliability.

[DRJDAN]

On Sat 119, I get 118 to 122 on the various transponders. On Sat 110, I get 96 to 102 on the various transponders.
Why is 119 stronger?
During a rain storm would a 120 hold the signal longrer than a 96? Do all channels go out in a rain storm or just ones on wear transponders?
How does the quad get the 18+ from the reciever?

I believe that 119 is stronger because it has higher power on more transponders. Also, the distance between the feedhorns on your quad may not be exactly ideal for your location. It sounds as though you've got the azimuth, elevation, and skew about as good as they can possibly be.

Yes, there should be a slight difference between the two; maybe a few more minutes before signal lock is lost. Rain can affect different transponder frequencies or polarizations differently,
and usually does. This is one reason why you sometimes lose some transponders first, rather than all of them at the same time.
I find that my signal usually cuts out rather suddenly and completely, when a heavy cloud passes by, and that the rain itself doesn't usually interfere with viewing, at least not for very long.

The DC power and switching voltages are delivered to the quad in the same way as for any other switch or LNBF. Each receiver (and possibly a separate power inserter, which preserves switching voltages) adds DC power onto the coaxial cable. The switching voltage is between the shield and the inner conductor.

[DRJDAN]

Why can the 301 give the power to the Quad without an inserter, but the two Duals with SW44 require the inserter?

You reference the feedhorns on the Quad. What is the feedhorns? Also, I do not have a Quad but two Duals and a SW44. Do the two Duals have the feedhorns issue?

I don't know whether a quad requires a power inserter, or not. If not, then its internal switch requires less power than the SW44 or SW64. This would be quite a design triumph.

The feedhorn on the LNBF is the conical (in this case) waveguide under the plastic cover cap. The quad has two integral LNBFs, which are spaced a fixed distance apart. This distance is designed to accept signals from two orbital slots spaced nine degrees apart in the geostationary arc (such as 119 and 110), on a DISH 500 located anywhere within the continental US, when the azimuth, elevation, and skew are set correctly for the specific location.

The selected distance cannot be perfectly ideal for every CONUS location. So, there may be some "spill" of one or both focused signal beams, either outside its feedhorn or along an edge. This can cause a loss of measured signal strength.

The same general design tradeoff also applies to two duals, which are held at a more-or-less fixed distance apart by a (somewhat flimsy) plastic Y-connector. However, there is some mechanical play available. It would also be feasible (though not cost effective :D ) to machine your own (aluminum?) Y-connector, with the ideal separation for your specific location, or perhaps even a separation adjustment. :rolleyes:

The quad does not require a power inserter. Only amplifiers if the receiver is over 75' from the quad.
