Rated 3 out of 5 by 7
Rated 3 out of 5 by buck56 Solid piece, but really need it?
Appears to be of good quality, but some complaints. Firstly, it is in 2 pieces, the outdoor booster, mounted to the antenna, and the indoor power supply. These should be combined into one indoor unit. Secondly, the switches should have been on the outside of the unit for easy setting (if you only use the booster for television, not FM, and you have only one antenna for both, you would not need to change the factory settings).
FM reception was significantly improved, but the digital television reception was not. I can only mount the antenna on the balcony. If I could mount the antenna on a different wall, I would not need a booster. Also, the unit should not cost over $50.

Rated 5 out of 5 by BuckinMontreal Fantastic preamp
I bought this preamplifier to replace an Antennas Direct PA18 preamplifier. Originally I decided to go with the PA18 because it was half the cost and in this case you get what you pay for. The PA18 was able to increase the signal strength but not enough on some of my weaker channels. With the CM7777 the signal quality on some previously marginal channels has increased from 1/10 bars to 7/10.
The only downside to this product is that it is expensive, no getting around that as it cost more than my antenna.
If you are looking for a preamp, save yourself the time and hassle, just bite the bullet and buy this one.

Rated 1 out of 5 by WatchingDog It does not help
After reading of some comments about it I decided to try this one, but finally I was very disappointed with it. Even changed all the coxial connection cables, the digital signal strength got no any improvment at all, looks like the signal just bypassed.

The picture on the Source and the description plainly shows an amplifier with separate VHF and UHF inputs, required for my setup. The picture and description is probably a Titan1, while i was shipped a Titan2. The Channel Master with its 30db gain was supposed to replace a DigiWave unit with only 15db gain. The CM 7777 received only the two strongest signals, and in fact was worse than bypassing the unit altogether. i returned the CM 7777.
