Amplify+ Adjustable Gain Preamplifier for Professionals

We are about 65 miles from the transmitters. We were experiencing signal loss quite a bit. I had purchased and installed the CM7777777777 or something or other, some years back. Not really sure why it stopped working, but it did. I installed the new one and it even picked up about 10 more channels on the scan. We now get 91 channels of which we watch maybe 10 different channels. I cut off cable about 12 years ago due to their price going up and up. DirecTV and the others get you started with a low monthly cost for 12 months and then the cost just keeps going up from there. Now with the new splitter installed we get the same channels in all the rooms. Thank you Channel Master for the help. I also use TIVO and it used to be great but now it seems to be nothing but a pain in the butt. Picture with no sound or sound with no picture nearly everyday. Have to reboot over and over! what's up with that?

Bought the CM-7778HD to replace a CM-7779HD because I needed to add a VHF antenna to my current antenna. Combined the antenna's and set the amplifier's gain to high setting and I am happy with the results. I have noticed an improvement in the VHF signal and the UHF works as before. To me Channel Master and Televes make the best antenna products.

I have a ClearStream MAX-V HDTV Antenna in my attic. ~50 miles away from the broadcast towers in Washington DC and over the Bull Run Mountains. I get about 80 channels (some of which I probably won't watch) but it works fantastic. The ClearStream has only two short VHF elements, but I can still get the VHF channels clearly. I might add my old school VHF antenna and split the UHF and VHF signals and see if that makes any difference.
My only issue is that the bracket to hold the amplifier on the ClearStream post isn't large enough for the ClearStream post. Maybe some wire ties will work.
Thanks Channel Master.Great job and I can recommend this product to anybody.

Easy to install and works, thankfully, as Channel Master says it will. Very stable signals on the weaker channels now that were intermittent. Watched for hours with no dropouts whatsoever.

Have had my CM 7778 for several years and use with a CM 4 way amplified splitter 30-ft away. So far it's worked well plus extremely well made and doesn't run nearly as warm as some other brands making it safer in an attic. The medium setting works best for me and even provides enough power that I'm able to run an extra 20-ft line to my neighbor's so they can tap into my system. Also helped end my interference problems from 2 nearby ham radios and jet communications. I'm guessing too I have less distortion in my line compared to a regular pre-amp that runs to a UHF/VHF combiner because it removes the need for that extra connection.
