Did my research two years ago, ended up with a CM4228 on a pole mounted on my chimney has worked great for two years now. Recently though KXAS, the local NBC channel has gotten very bad. It will not come in consistently. Its weird, and the only channel(s) that I have any issues with. I have a hdomerun and looking at the signal meter for any other channel the signal strength, signal quality and symbol quality are all hovering around 100%. KXAS is in the yellow in the 60's for signal quality, the 50's for signal quality (but will periodically drop to 0) and symbol quality is all over the place from 0-100.

Any thoughts on what could be go on? All transmitters are basically in the same place in Dallas so its weird that this one channel is a problem.
