    Default Channel Master 7777-HD adjustable gain preamp indoor/outdoor

    I would be grateful for comments about how this compares with other products, CM or other brands, etc.

    Which model do you have? What year was it manufactured? To the worst of my knowledge CM has now unveiled a third edition of this pre amp. I have an original model which has a separate input for a UHF antenna and a separate input for a VHF antenna. The newer models have a single combo input that handles a single UHF/VHF antenna.
