    • ANTENNA MIRACLE
I AM LOCATED MIDWAY BETWEEN TWO MARKETS MAKING MOST TOWERS 60 PLUS MILES AWAY. RECEPTION WAS SPOTTY AND UNRELIABLE. AFTER INSTALLING THIS AMPLIFIER I PICK UP CHANNELS FROM BOTH MARKETS AND IT IS A RELIABLE CLEAR SIGNAL. SCANNED 15 CHANNELS BEFORE AMPLIFIER WITH INCONSISTENT SIGNAL. AFTER AMPLIFIER I SCANNED 102. THAT WAS A PLEASANT SURPRISE. UNIT IS A LITTLE PRICY BUT IT WORKED WELL FOR ME. ... show more

    • The HONEST review Channel Master CM-7778HD
Though this is a good amp it is only recommended if you have ONE outdoor antenna. It has the option to connect a VHF and UHF separately but it had a real hard time getting good signal on each of the seperate ports. It worked better just combining the antenna itself and connecting it to just the one UHF/VHF port. It is nice that it has a low and high gain giving you two types of gain to test. Biggest problem with these amps is it blows up all signal in whole. This means channels that don’t need this amp will get distorted because now the signal is too high. It worked decently with the Channel Master Omnidirectional antenna but it did not solve the issues of fixing low signals while keeping good higher signals. For my location I ended up returning and getting a Televes amp which balances all signals. The difference was exceptional compared to this Channel Master. For me I am located in New England near New Haven and NYC. ... show more

    • The Best Antenna Pre-Amplifier, Channel Master CM-7778HD!!
I bought this to replace a 5 year old antennas direct preamp, I was losing channels with the antennas direct preamp. The CM7778HD seemed like what I needed. I am in a deep fringe area (in a valley with hills and trees keeping from line of sight to towers) about 40 miles from any TV towers plus I have a 50 foot run of coax to tha antennas and split to 3 TV’s in the house. I hooked up the CM7778HD with separate UHF and VHF antennas set on the high gain setting, turns out it was too much on the high gain setting due to interference on some channels that were clear before on the old pre amp. I changed the CM7778HD to the low gain setting and I am getting all channels that are reachable in my area. The CM7778HD is a great pre amplifier, made very well and easy to install. ... show more

    • Excellent Purchase
This was just what I needed. I had tried a couple of different, lower priced boosters without much success. With the two others I purchased recently the channels would come in sometimes but not every time. But with this Channel Master CM-7778HD I was shocked how good it was. In my area there are a total of four major channels of networks (ABC, NBC, CBS, Fox) including their sub-channels and some independent stations, I have 37 channels to watch now. The NBC affiliate is 70 miles from me. All come in clear. I live in an upstairs apartment, and I use a ClearStream antenna. Although occasionally the weather will cause issues (storms) the rest of the time the channels are clear. I recommend you purchase this product and don't mess with the cheaper versions. ... show more

    • I think it works better then the other brands I own....I think
This Adjustable Gain Amplifier has two adjustments (high/low), not variable. To change the Gain or the FM Trap or the Duel to Single antenna input selection requires one to open the unit removing four screws. It could be a problem if mounted on the antenna mast. I think a sealed flip-up access door would be better served. ... show more

    • Powerful, but way too noisy, VHF does not work at all.
One thing this did somewhat well was boost the strength of adjacent market channels. Unfortunately, this product also increased noised on all channels and does not have a good noise floor. On my HDHomeRun monitor, I had stations that were marginal strength (Around 55-65) to to moderate strength (75-85), but this also caused SNR to tank from around 55-65 to right at 50 or just below, which made most of these stations inaudible to receivers. So, while it increased strength, it dramatically increased noise. I have an existing preamp from Wingard , it does not boost as much but it also is low noise and does not cause additional noise. So, I am torn, but I have to send this back and deal with the occasional low signal of these distant channels. Also, the VHF toggle is a joke, when using the combined input, it basically filters out the VHF channels. For this reason, I feel the unit is defective. ... show more

    • Great Product !
This amplifier is professional grade and highly recommended for pulling in a good strong quality TV over the air signal. Especially when TV towers are 30 or 40 miles or away from antenna location. This amp allows user to prevent or allow FM to be picked up. Also has adjustable high or low gain switch. Very easy to install , well made. Very pleased with this channel Master product. With out it , can only get 8 local channels. With amp can get 46 channels . I live in an rural area that is relatively hilly . I'm fortunate that there are relatively few trees next to outdoor antenna, and have a clear path towards Tv towers. ... show more
