Channel Master - A Name You Can Trust!!!

The Channel Master CM 7777 is a high gain, low noise preamplifier used for weak signal areas to allow a weak signal that is present at the antenna to be amplified in order to get it through the cable to the TV set. Also, if your coaxial run from your antenna to your TV set is fairly long, a preamplifier may be necessary to optimize your reception. This TV antenna preamplifier works best in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal areas the CM 7778 is a better choice.

A must have for rural areas
The CM7777 preamplifier does an amazing job bringing in channels in rural areas. I'm approximately 75 miles from the bulk of TV stations so this works great for us. It works so well I cancelled our satellite TV service. I point my antenna in one direction and get 50 channels. But, there is one down side to it: it doesn't like lightning, even though my antenna is grounded, lightning will get it. But that's like every two years. So, go ahead and get yours from the folks you can count on; Summit Source.
