Before I put my rotor up on my antenna, I was actually getting a better signal from some sources. Now that rotor is up, I'm getting better on some channels, but worse on others, and multipathing is real problem. Part of that, I'm sure, is the terrain between me and the towers (I'm in a valley) but I also noticed that I've got a little nick in the RG6 cable where I pulled it into the house. Can this seriously degrade the signal strength? I can always pull a little of the cable out, cut out the nicked part, and put a new F-connector on it, but wondered how serious this can be before I go through the effort.
