The LNB is not at the base of the dish. That is the module on the end of the arm in front of the dish. It sounds like you might have two legacy LNB on this setup. You could try bypassing the modules at the base of the dish and feed the receiver direct. The signal from one LNB should 91. The signal from the other LNB should be 82.

I think we're talking about the same thing, but I'm describing it differently (pic below). Owner bought a new one, and we swapped them out in various combinations, with the scenario unchanged. (Unless you're describing something inside the module shown, which can also be individually replaced.)

There are indeed 2 separate ones, and have been in place 15-20 years, so the legacy aspect is a good call.

Be sure to perform a check switch after every change to the setup. It might be necessary to disconnect the RG6(s) from the receiver, perform a check switch to clear the settings, then reconnect them and perform another check switch.

Yes we are talking about the same thing. Sometimes they mount "switches" onto the back of the dish and I thought you might be referring to those.

Mounting on a tree is not the best for the tree but would work. A 4x4 wood or a sturdy metal post the same diameter as the dish j-mount might be better. Be aware that the dish does not need to be mounted very high up, just high enough to avoid temporary obstacles such as snow drifts, vehicles, animals, humans, etc.

I usually use 1" black PVC or larger for small cables. Smaller conduit might work but conduit that is too small increases friction and the possibility of cable damage. Larger conduit may be required for more than two RG6 cables. Black PVC conduit is usually available in up to 100' coils at plumbing or building supply stores. Direct burial cable is another option but is more susceptible to physical damage.

Hi Guys,

I have mounted a new Bell Dish closer to the building and Bell 6500 HD receiver that was to far ( 250 feet +) the original dish. When pointing the new dish, I used a single legacy LNB on 91 side of the yoke (as I was awaiting a new DPP Quad that I ordered). Signal was good at 93 %. After installing the new DPP Quad and running a check switch with no satellite cable connected at receiver and then another with the satellite cable connected, I am only getting the 91 satellite at a signal strength of 93 %. Azimuth and elevation are set for my area. Tried raising elevation by 2 degrees. Mast is not perfectly plumb and out by 2 degrees. I compensated for this by rotating skew setting an additional 2 degrees from recommended 98.6 degrees. Any ideas why I am not picking up 82? Thanks again.

Did you try disconnecting the coax and performing a check switch to clear the data, and then connecting the coax and performing a check switch again?

Yes. I removed RG6 cable at receiver and performed a check switch. This gave me a no reception message. I then reconnected cable and performed another check switch which recognized DPP Quad but only found satellite 91 on port 1. Could my dish alignment be my issue?

 

[ExDilbert]

Aiming the 91 LNB at 82 or 82 at 91 is a common issue that could lead to only seeing one satellite. It doesn't sound likely in this case due to the way the dish was aimed. Another possibility is that a round 18" dish is being used instead of the oval 20" dish but, again, it's unlikely. Was a 4100 receiver tried at this location?

It’s a 20” dish that I installed. Originally I used a SD 4100 receiver with a short installation cable and TV set up next to the dish to point it. At time of installation I was using a single Legacy LNB installed in the 91 side of the yoke. DPP Quad is now installed to pick up both satellites. Thanks again

 

[ExDilbert]

I'm wondering what the 4100 sees with the DPP Quad.

 

[TMAN1]

I'm wondering what the 4100 sees with the DPP Quad.

SD 4100 and HD 6500 are both only getting signal on 91. Is it possible for a tree branch to block 1 satellite and not the other?

 

[ExDilbert]

Is it possible for a tree branch to block 1 satellite and not the other?

Yes. The satellites are just far enough apart for this to be possible.

 

[TMAN1]

Yes. The satellites are just far enough apart for this to be possible.

If I am unable to get a signal on 82 satellite, will this new HD receiver just not have HD channels and work without issues using only the 91? I’m guessing it will have the same channels as the previous 4100? Thanks again.

 

[jdevlin]

It should work just fine with 91 only except for the loss of HD.

Thank you!

Would there be an issue with reliability or signal quality from having short cables from the LNB connectors through the arm and either attached to the base of the mast or under the roof overhang and then using a F to F connector between it and the cable running into the house? Basically, a way to pre-cable the LNBs before mounting the dish and have an easy access point for cable changes, testing, etc. without having to get to the LNBs.

 

[jdevlin]

All my units are setup exactly like that. I have no issues.

 

[LWP]

Perfect, thanks!

Hello ,

I have just installed a new dish equipped with a quad output dpp lnb. I’m having signal problems and am looking for answers and help. I presently see sat 82 and see many but not all of my stations. I assume that I need to fine tune my dish angles. Is this correct ? Also, I do not see sat 91. I was under the impression that using the “Y” yolk, obtaining a signal from both would be “automatic”. What else do I need to do to see it. One final piece to the puzzle; the quad dpp has a built in switch ….. so my coax are connecting to ports 1 and 2. I assume this ok. Is this correct ? A lot of assumptions, I need to validate …. Or change these. Can someone offer the appropriate info and / or help ??

Thanks in advance !

It is possible to have the dish aimed to only receive one satellite. Since only see 82 It is likely you need to re-aim the dish.
Until you get the proper aim for both satellites you will not get all the channels.
