Well, I installed the new balun CM-94444 this afternoon. Because the new balun leads mount on top and fall on either side of the CM-5030 antenna frame, I felt I should not shorten the balun leads. I...

rabbit73, for your suggestion of a pre-amp, would the Channel Master CM-7777HD be a good choice?

Thanks for your input, jrgagne99. Is a "Digital cliff" referring to where the TV signal just drops off?
