5 of 5 Excellent Amplifier August 6, 2019
Reviewer: JD  
This amplifier is great for strengthening signals in already strong areas. I tried this model and it worked much better than the cm 7777 for me.

5 of 5 7778 March 22, 2019
Reviewer: Anonymous Person  
Was easy to install, works great. Now i can use a smaller antenna on my roof that birds cant roost on. Had a large antenna that worked good, but birds roosted on it and messed up roof. The only additional things i had to get were 2 short co axial cables.

5 of 5 Medium Gain Pre-amp GREAT for antenna-TV March 22, 2019
Reviewer: John E from Atlanta, GA  
I live in a small town about 25 miles west of downtown Atlanta. Of course all the major TV transmitters are on the east side of Atlanta (50-60 miles). I had an old Archer pre-amp that did OK, but this new CM Medium Gain unit now brings in more channels and with more clear resolution.

5 of 5 Beware of over-amplication December 19, 2018
Reviewer: Vernon from Augusta GA  
I had the CM-7777 high gain preamp for years, and did not know that there was a better choice for my rooftop antenna, until I carefully read the info on the Channel Master website. I soon discovered that with the PBS station 47 miles away and the rest of the local stations 16 miles or less, the medium gain preamp CM-7778 is a better choice. I now get a better picture, with more deeply saturated color. I understand there may have been an issue with over-amplication with the high gain preamp, that was not obvious, as I had thought the  more gain, the better. I am actually amazed at the difference.

5 of 5 Brought my weak channels in much better May 31, 2018
Reviewer: jbizzle from Northeast Georgia  
I live about 40 miles northeast of Atlanta transmit towers.  I have an RCA 60 mile uni-direction antenna mounted about 25-30ft above ground.  I was picking up NBC and FOX relatively good but bad weather sometimes made it difficult.  ABC was the hardest to pinpoint with my antenna rotator and most of the the time would not even come in.  Adding this amp brought in all three networks with NO antenna rotation necessary!
This is a big help because when my Channel Master DVR + is set to record on a certain station, I have to make sure that station is tuned in.  Many times the recording is horrible because fade out or non-existent.  Those days are over now thanks to the Titan 2!   And re-scanning brought in channels I didn't know existed!
