Product Description

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 to a viewable strength. This TV antenna preamplifier works best for persons in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal areas our medium gain preamplifier, the CM 7778 is a better choice.

I purchased this amp over a year ago and found that it was just the ticket. I researched my purchase on several websites and determined this was the best within an afordable range (There was one overseas with less noise but it was over double the cost). I had a cheap amp from a home improvement store that gave me reception but with the upgrade to HDTV I was getting dropouts more than I would like. I purchased this amp and no more drop outs, it gave me a boost in 20 points on my Sony Bravia digital reception over the cheapo booster. I suspect the negative reviewer installed it wrong. There are separate inputs for VHF & UHF that you can combine to one input but if you do not you would eliminate your VHF channels (2-13) or UHF (13-69) entirely which would explain loss of these channels.

UPDATE 1 May 2010: With the analog shutoff now history, and every analog TV without a converter box or cable showing 68 channels of snow, the local strong station WMBC is now gone. I replaced the antennacraft 10G212 preamp with the CM7777. Due to three stations (7,11,13) moving back to high VHF I had to get a high VHF antenna. I got a Winegard YA1713. The 7777 has a separate VHF input which allows you to combine the two antennas with less loss than if you used a splitter.

The lower noise figure of 2dB allows me to get a stronger signal on my weak station (WNYW FOX 5). It still drops out a bit but it is better than with the Antennacraft preamp.

One more thing - just be careful when tightening the screws in the preamp (if you've opened it to switch from combined VHF/UHF to separate or to switch off the FM trap). I broke one screw because I tightened it too much.

Also don't use the rubber boots if you are using compression F connectors. They won't fit. Discard the boots and get some self vulcanizing silicone tape (rescue tape) instead to seal off your connectors. Compression F connectors are pretty water resistant anyway but the silicone tape adds that extra layer of protection.

Old review:

I live in Northwest NJ (Sussex/Wantage), which is a deep fringe area because it is blocked by hills and 49 miles from the empire state building.

I am a ham radio operator and have an 86 foot tower for ham radio use. My CM4228 is there, as is this CM7777 preamp.

Build quality of this preamp is good. The casing is made of metal unlike many of the others which are cheap and made of plastic.

Performance is good. It helps me overcome the cable loss of 210' of RG6 cable and helps pull in the weak signals from New York and Philadelphia.

I like that it has separate inputs for VHF/UHF.

But this pre-amp made me lose channel 25-1 (physical 24) and gave me dropouts on some other channels which were previously dropout free. No matter how I adjusted the antenna it did not pick up these lost channels. Previously I had an Antennacraft 10G212 which pulled in almost everything. The Antennacraft is also about half the price of the CM7777. I suspect it can't handle the overload from the nearby (~15mi) WMBC analog which contains zero programming that interests me. The good news is that WMBC is moving away come 02/17/09 so hopefully it will get a little better.

Channel Master used to be a great company that had some really great products, when they were owned by Andrew Corp. I have quite a few products from Andrew and their build quality is excellent. But CM had to be sold off when Commscope bought out Andrew, and last I heard CM closed their last US plant this year. So unfortunately I think the once great company Channel Master will be gone soon. The name will remain, but the products just won't be the same anymore.

I've got to believe the reviewer that had problems didn't hook this thing up correctly or follow the directions. I did the same thing myself and the results were awful. When following the directions, however, the results are simply amazing. I get stations - both analog and especially digital that I couldn't get before. I didn't do a signal strength comparison, but I'm guessing that it must at least double the signal. I called Channelmaster and talked to a real person in North Carolina who helped me prior to the sale. I ordered from Crutchfield's and got the unit the next day with standard shipping. I'm getting signals that, according to [...], show that I'm 20 to 30 miles closer to the towers. I could not be more pleased, and would recommend channelmaster products and Crutchfields anytime.
