I've got a 622 that has been working for close to 2 years. Up till now, I've just had a decent antenna mounted to the backside of my TV Console. It drops out at times, especially during the fall. I've decided to mount an antenna on the same pole as my dish outside. So, I bought some diplexers and new RG6 cables, and took the antenna up onto the roof where my dish is. Plugged in everything and ... no signal. No OTA signal at all. So, tried a different antenna outside. Still no signal.

So let me describe my setup as best I can and hopefully someone can help.

On the roof are 2 dishes: one is the larger one, and the other is a small round one. I used to be connected to 110, 118, 119, and 129, but a tree blocked 129, so they brought in another dish to be able to see 61.5. I have a DPP44 bringing everything to the side of my house. Just below the DPP44 I put a diplexer to merge together the OTA antenna and the satellite signal.
On the side of my house, before the cables enter the crawl space, there is another diplexer which distributes my TV2 throughout the house.
Inside my living room is the cable coming from the wall, which I connected to a diplexer. The ANT side goes into the OTA connection on the back of my 622. The SAT side is connected to another diplexer (the same one that Dish installed for the TV2 distribution (TV side connected to the InHouse Dist connection on the 622, SAT goes to the DPPlus Separator). The Separator goes into the Sat 1 and Sat 2 connection on the back of the 622.

Anyone see anywhere I'm going wrong?

Thanks in advance!

It sounds like you are trying to diplex into a cable that already had a diplexer for the feed for TV2.

I do not think you need so many diplexers. If you can get your OTA lead to the diplexer at the crawl space entrance, just use a 3-way splitter on the TV side to combine OTA signal with TV2 signal. Add a 3-way splitter on TV side of diplexer at the rear of SAT Revr with a lead going to TV2 and OTA input respectively.

This should work if you have enough OTA signal strength. You will lose approx 6 db of signal using the splitters. If you were getting pretty good reception before with indoor antenna, it sounds like you should receive a pretty strong signal with a good outdoor antenna and be able to withstand the 6 db hit.

Remember, too strong a digital signal is just as bad as too low a signal. I had this problem with my OTA reception and had to install a variable attenuator in my feed line and adjust for best signal quality. Without the attenuator I was getting a no signal error from my tuner.

Hope this helps. A too strong signal may be your only problem.
