I have been having reception issues on my local ABC and its sub-channel. My setup is a two antenna setup. I have an Antennas Direct C2V pointed toward all towers except Fox (it is in a completely different direction). I am using an Antennas Direct 91XG to pull in Fox. I just recently had both antennas combined using this custom combiner:

The combined output ran to a Channel Master 3414:

That is then ran out to 3 television sets. I had experienced some trouble with the new Channel Master DVR+ that I was hoping the Tinlee AC7 combiner would solve. But, unfortunately it didn't. The Tivo Roamio I have hooked up was not having any of the same problems the DVR+ has with the same setup. I began problem-solving to make sure that the tuners on the Channel Master DVR+ weren't being overpowered (which they weren't). I can't add a preamp to the Antennas Direct C2V (that's where the ABC stations are coming from) because when I ordered the custom AC7 combiner I only had DC pass built in for the Fox station from the Antennas Direct 91XG (because according to my TVFool report it is my weakest station). I had this amp laying around from an earlier setup:

I decided then to run the combined output from both antennas into the Skywalker amp (it has a nob to control amount of amplification; I did not turn it up all the way), then from there to the Channel Master 3414 amp and split to the 3 TV's. Then voila. The ABC channels stabilized and my Fox station signal quality has jumped up to 84% signal strength and mid 90's signal quality. Unfortunately, the stabilization of ABC and its sub-channel (33.2) only lasted a couple of days. Now, the signal quality meter on the Channel Master DVR+ is back to fluctuating quite a bit. Hence, the picture difficulties on said channels.
So, I am looking for help with this situation. One TV only connected to a coaxial line doesn't have the problem. Another set connected to a Tivo Roamio hasn't had the problem. I'm not sure what to make of it. I'm wondering if there is an issue that the DVR+ is detecting because it is more sensitive but don't know what it could be.
