92XX/94XX Installation 101 - Canadian TV, Computing and Home Theatre Forums

Having read the topics of attaining satellite 82 after receiving satellite 91 the consensus seemed to be to find a strong signal on 91 then using your skew to find satellite 82. I have tried for five days between work (no luck). I have got 82 but lost 91 in the process. Anyway is there anyone who has been thru the same problems and how to attain Sat 91 and 82 at the same time. If so is it possible as a scenario to state something like yes we had Sat 91 then moved the Skew 14 degrees clockwise or something. I think this would be more informative than to just move your skew and hope you luck out.

Hi Guys,

I'm upgrading my current Bell SD 4100 receivers to Bell HD 6500's. I'm having an issue getting one of the two new Bell 6500 HD receivers to work. It looks like its due to a long cable run between LNB and receiver. I'm using a DPP quad LNB with about 250 feet of RG6 to the receiver that isn't working. My other HD 6500 receiver fed from the same DPP quad LNB that is working has a shorter cable run of about 80 feet and has great signal on both 82 and 91 satellites. The original SD 4100 works perfect on the longer cable run. The new HD 6500 is not locking on the 82 satellite. I have tried switching ports on LNB and using a 20db inline satellite amplifier. Any help would be greatly appreciated. Thanks.
Has switching the receivers been tried? If that fails, try checking the connections for leakage or corrosion and replacing them with good compression connectors if needed. Don't know the setup but installing a DPP switch at a point closer to both receivers may help. Satellite signal amplifiers may be available for long cable runs. If that route is taken, make sure it is designed for Dish/Bell DPP equipment. Another option may be to install a lower loss cable such as RG11.
Thanks for the help! Switching new HD receivers has been tried. No change. Only the original SD 4100 receiver will work. SD 4100 locks on to satellite 91 with about 96% signal strength. LNB is DPP Quad which to my understanding should not need any switches. Same dish and DPP Quad LNB on my other new HD 6500 receiver using a shorter cable run of about 80 feet works great with 82 and 91 satellite signal strength in the high 90 %. The longer RG6 cable is about 250 feet. Cable connector ends look good. If cable quality or condition was the issue should this not also be a problem for the SD 4100 ?
Some receivers are more sensitive and there may be other issues such as DC voltage drop on the line to power the LNB. A switch may be beneficial if it results in a shorter length of cable to the more distant receiver. It may also boost the signal and provide a better DC voltage level to the LNB. Don't know the exact layout but if adding a switch results in an 80' shorter run to the more distant receiver then it may help. It may also allow the addition of more receivers with less RG6.
Just to clarify. What type of switch would I need to install and at what point In the 250 foot RG6 cable run? Approximately 2/3 of the cable is buried. Would this require a different LNB set up than the current DPP Quad? Possibly Legacy LNB’s with a switch 44.? Thanks again for the help
A DPP44 switch is required for the DPP Quad LNB. The use of the switch depends on the two cables going to a common location that is closer to the distant receiver. If they don't then the a line amp would likely be a better solution. That would need to be placed as close to the dish as possible. If neither of those works then I would look at another solution such as upgraded wiring. First, I would look into what might be causing any possible issue with the current wiring such as voltage drop, damage or water ingress. That might determine what type of cable could make improvements.
Do all DPP Quad LNB’s require a DPP Switch 44 or is this only required to boost the voltage to the LNB with the long cable run? My current set up does not have any external switches and is working with the shorter run. Both cables from the Quad LNB to each receiver do run to a common location that would shorten my longer cable run by about 50 feet. 110 Volt receptacle is also available for power. Thanks again!
A switch is not usually required for up to four receivers but it should solve the issue in this case by providing more stable power to the LNB and shortening the long run of RG6. That assumes that the issue is simply due to cable length and not something else.
When installing the DPP SW 44, how many ports will need to be utilized on the DPP Quad LNB? I’m assuming I will need 2 cables between LNB and SW 44 to pick up both 91 and 82 ? Also, would the DPP SW 44 serve as a grounding point for the RG6 cables? I’m not 100 % sure both RG6 cables are currently grounded?

Thanks again
If you need 4 outputs, you can also get a way with it by using a DPP Twin LNB (which has 2 outputs) instead of a Quad LNB, and then connect the two outputs to a DPP 44 Switch, then it will give you 4 outputs from the switch to your 4 receivers.

Some people might want to do it this way it might be cleaner, less wires running from the dish, and then you can have longer runs because the switch does kind of boost the signal a bit.
Thanks for the help! I’m only needing 2 HD single tuner Bell 6500 receivers to work. I currently have 1 working without any issues. However, my second receiver that is on a longer RG6 run of about 250 feet will not pick up both satellites? The SD 4100 receiver it is replacing works without any issues….. I’m hoping the DPP SW 44 will do the trick?
then yes the switch will work but remember, you need two lines into the switch but you can use 2 lines out instead of 4
its official name is DPP44 Switch, to avoid confusion

Thanks! I did order a DPP44 switch today. Not 💯 sure on the 3ghz cable rating? However, The current 250 foot RG6 cable and Quad LNB work for the 4100 SD receiver without any issues?

by the way, is the super long cable run, is it one continuous cable, is it a 3 ghz rated coax, any splices in it? is it terminated with snap and seal weather proof connectors? those also will be a factor about it working or not but as others have suspected, it might very well be a voltage drop due to the long distance.
I do have 1 splice. What is the best way to check for voltage drop?
One possibility is older receivers and switches did not need to have 3ghz cable runs because they did not need the extra bandwidth for band stacking. DPP packs more frequencies on the same wire thus they need 3ghz cables so its also could possibly be one factor. It could still work with older spec cables, but it means the cable is not tested at those frequencies so it may have lower signal or voltage drops perhaps?
Good explanation! I know that the buried RG6 cable was installed in 2008. That being said, do you think that because the SD receiver works with such a good signal that I need to worry about checking connections any further?
The RG6 only needs to be rated for 2.4GHz. 3GHz won't hurt and it might help. Other things such as copper core and shield instead of copper coated steel and aluminum helps with longer runs as well.

1761 is right about the cable stacking. Legacy equipment uses frequencies from about 1GHz to 1.6GHz. DPP pushes the top end to about 2.2GHz which is why 2.4GHz or higher RG6 is used. I assume the DPP44 and 4100 receiver used stacking since I think the 4100 is DPP compatible. If legacy LNBs were previously used then that could explain the loss of 82 on the long run with the DPP LNB and new receivers.
Great info Guys! I Appreciate it! The SD 4100 works great with the original Legacy LNB and the newly installed DPP Quad. When I received new HD receivers, I replaced the Legacy LNB first with a DPP Twin and then the DPP Quad in attempts to get the new HD receiver on the longer cable run working. As of now I am waiting for my DPP 44 switch to try with the DPP Quad….. In order to make the DPP 44 work, I will need to cut the RG6 from dish to receiver. Will adding this splice have any negative effects to the long RG6 run if the DPP switch doesn’t work and I need to splice it back together? Thanks again!
Barrel connectors are rated at about a 0.5 dB loss, which is usually insignificant, and the potential of a DC voltage drop if the connections become oxidized. They also need to be rated at 2.4GHz or higher.
Would Legacy LNB’s with a SW 44 and power inserter offer a better solution than a DPP Quad with DPP 44 switch for the long cable run?
Don't know because there are so many variables. Just be aware that DPP and legacy components such as LNBs and switches cannot be mixed. Most newer receivers should work with legacy or DPP but some, like the 9500, may require DPP for technical reasons. Unless there are reasons why it cannot be done, installing a dish at the other location might be the best solution.
Thanks again. DPP switch 44 arrived today. I’ll give it a try and post results. Is the function of the power inserter to boost voltage to LNB or simply power the DPP switch 44?
It does both.
So I installed the new DPP 44 switch with power inserter and must have done something incorrectly as I lost signal to the receiver that was originally working and the receiver on the long cable run is still not working. I followed the instructions and made good connections at switch and power inserter. I ran a check switch and had neither the 91 or 82. Only thing I question is whether it matters which ports I use at the DPP QUAD LNB. I am currently using ports 1 and 2 at DPP QUAD LNB. Please see picture of switch. Note, Switch is currently by passed and back to running directly from LNB to receivers.

I was using the ports that are uncapped. TO DISH ports1 and 2 of switch ran to ports 1 and 2 of DPP QUAD LNB. To receiver port 2 of switch ran to receiver that was originally working (shorter cable run). To receiver satellite in port on power inserter ran to receiver on the the longer cable run. Hope this all makes sense?? . Any help would be greatly appreciated. Thanks again!
Hi Guys,

When installing a DPP 44 switch using a DPP QUAD LNB, does it matter which 2 ports are used on the LNB? Currently can’t get it to work using ports 1 and 2? Thanks in advance.
Using the closest receiver, I would disconnect the receiver at the switch and perform a check switch with no connection. Then I would connect the receiver to the " to receiver" connection of the power inserter and then perform another check switch.
OK. Trying that now. So the DPP 44 Switch doesn’t care which if the 4 ports the DPP LNB are used?

Thanks again!

Thanks again. I Followed the above instructions and now both receivers are working. However, I only have satellite 82 and high def channels on the shorter cable run receiver and 91 and SD channels only on the longer run HD receiver? Also appears that the longer cable run picking up 91 isn’t seeing the DPP 44 switch ? Any ideas? Thanks

The issue with the shorter run is puzzling, especially since both satellites show up on the scan. The issues with the longer run could be due to cable loss. More troubleshooting is required. What happens when the receivers are switched? What are the results with a 4100 receiver? What are the results with the line amp, which must be DPP compatible to work properly, connected to the switch output going to the most distant receiver?

Is it possible to test the receivers with a known to be working dish installation elsewhere?
I haven’t tried switching the HD receivers since installing the DPP44 switch. The SD 4100 receiver is connected directly to the #3 port of the DPP LNB and picks up both 91 and 82. When the SD 4100 was connected to the DPP switch 44 it would not work? I am not sure whether the line amp I tried is DPP compatible? Does it matter which 2 of the 4 ports at the DPP LNB are used to bring satellite signal to the switch? Please see pictures of line amp and 4100. Thanks again!

On second thought, there may be an issue with the line amp. It needs to pass DC from the receiver unchanged. To do that it must be powered separately or use the receiver's power and pass it through. I couldn't find any information on that exact amp but there are similar amps made for DPP so it's unknown if it is fully compatible.
Ok Thanks! I actually tried the DPP 44 Switch installation with and without the line amp. It didn’t seem to help with either scenario. My last update with pics did not have the line amp installed. The DPP switch 44 did help getting the new receiver to pick up 91 with 100% signal strength on the long cable run. I just don’t understand why it can’t pick up 82 on the long run? Also not understanding why my other receiver with the DPP switch 44 now only locks on to 82 and not 91? Wondering if I just need to go back to using the DPP quad without using DPP 44 for the HD 6500 and SD 4100 and then mount another dish to eliminate the long cable run to the other new HD 6500? This is how it’s currently connected.

I don't see any issues with the connections. If the 4100s work then it must be an issue with the new receivers. Someone on site will be better able to diagnose the issues and get it working. I'd still recommend a second dish if that is possible. 250' is about the limit for RG6 with typical satellite equipment. It's quite possible that the frequencies used for stacking with DPP is causing signal loss or other issues.
Thanks a lot for all your help and advice! I appreciate it and will let you know when I get it figured out. I’m thinking a new dish for the long cable run might be the way to go. Due to surrounding trees I might have to do a remote post mount. Is mounting to the base of a large cedar tree a bad idea? What’s the best conduit to run the RG6 back to the building with the receiver?
