Thread: 622 coax output w/ RF combiner

Oh and P.S.

If you're going to boost, boost before it becomes snowy. Once snowy then you've lost signal and you are but boosting the week and incomplete signal. If you think your 80 feed is too low, don't boost it at the far end, boost it behind the 622 or at the wall before it goes down (or up) to your closet. That's why OTA antenna amps are mast mounted amps or pre-amps. Booting the OTA signal after it's run 100' is like trying to restore a 300 year old painting. You can see it but just exactly was in those cracks?

The picture is snowy, with no noticeable diagonal pattern. When I remove the Comcast signal from the RF combiner, the picture clears up, which leads me to believe the channel 80 modulated signal is strong enough by itself, but is being overpowered by the amplified Comcast signal. I'm going to try the notch filter first. If that doesn't work or bleeds into other channels, then I will experiment with some combination of amplifier and attenuator as you suggested. Thanks for all the info! I'll let you know how it turns out.

I received the NF-471 notch filter and got everything connected. Everything appeared to be working great until I tested my digitals and some of them were gone. The filter was only supposed to go through channel 80, but it also removed my digital channels on 81. I decided to exchange it for the NF-470 filter, which removes channels 70-75, and modulate on 73. I lose a few analog cable channels, but keep all the digital locals and don't have to worry about getting power to any additional amplifiers. For the amount of time I actually spend watching cable on my secondary TV's, I doubt I will ever notice that ABC Family, Big 10 Network, and BET are gone. Thanks for all your help!
