Product Description
The Channel Master CM-7777V3 Titan 2 television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This preamplifier 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 is designed for use in the weakest of signal areas only. Keep in mind, due to its ultra high gain amplification, it can be subject to overdriving issues when used in areas with fairly strong signals present. In areas with a mix of both strong and weak signals, the Channel Master CM-7778V3 Titan 2 Medium Gain Preamplifier is a better choice. Preamplifiers are also used if you anticipate distributing your signal with a digital splitter to multiple televisions throughout your house as splitters reduce the signal strength available at each output.

However, others say that they have lost all channels or that they dropped a large number of channels.
"...This is held in high regard in that it amplifies without causing further issues...." Read more
"...So after installation I tested the antenna and only received about 12 channels...." Read more
"...This preamp has a specified 1 dB Noise Figure, separately amplifies both VHF and UHF signals, and advertises a typical 18dB gain in the VHF/UHF band...." Read more
"...I went from getting a few channels, to no channels at all. But of course I didn't suspect the unit itself to be at fault, but me...." Read more
Customers are mixed about the value of the antenna. Some mention it's worth the money to amp up the digital signal from their antenna, while others say that it'll be a waste of money.
"...The published results were not pretty... none of the TV stations were green. All were pink (weak)...." Read more
"...I'm glad I did cause I now have 13 channels I can watch. Well worth it in my opinion." Read more
"...CM-7777 preamp, the UHF channels were intermittent and choppy, barely watchable...." Read more
"...My old power supply was model 0747. It worked. This new one is a joke. The nearest tower to me is 76 miles away...." Read more
Customers are mixed about the picture quality of the antenna. Some mention that it improves picture quality, while others say that it pixelates and drops completely out of all channels.
"...review about its noise figure, but on digital channels the picture was free of pixelation from 300 kW transmitters 100 miles away...." Read more
"...Yagi style antenna in the attic, I did not get decent reception, picture was tiled and unstable, no signal from NBC nor ABC...." Read more
"...Wham hd tv without paying. Beautiful picture and clearity without cable. I would have never belief this possible...." Read more
"...I now have 18 stations rock steady. HD is much more vivid than cable or sat tv. This give me TV at a most reasonable price. Thanks again Amazon." Read more
Customers are dissatisfied with the durability of the antenna. They mention that it just doesn't last past a few months, it went out in 2 months, and that it's very failure prone. The unprotected electronics make the life of this unit short. Some say that the antenna arrived dead and that the warranty expired 2 days after they first installed it.
"...it, it worked great, but then, like a few other reviews, it died after just an hour or so of operation...." Read more
"...But, after two weeks, the unit was completely dead; no tv signal could be received...." Read more

This thing is GREAT for getting more range / more channels in fringe / deep fringe areas.
This thing will not work in (sub-)urban areas or as a distribution amp.
Pros_________________Cons:
- red hot gain - no gain control to make it more forgiving of overloads
- sturdy casing - mine wouldn't open so I couldn't change the FM trap setting
- value - crummy warranty (seriously?? 90 days??)
This thing's greatest strength -- gain -- is its weakness. If you live within 30 miles of a powerful FM or TV transmitter, airport, or military base, it will get hopelessly overloaded (even decreasing the signal). That means nearly all metro areas and many suburbanites should buy something else (look at the Kitz Tech amps, which have a nice gain control). I tested the Channel Master against 3 other high gain amps, and this one came out best of the bunch. Unfortunately, there aren't any analog signals in my area so I can't give you any qualitative review about its noise figure, but on digital channels the picture was free of pixelation from 300 kW transmitters 100 miles away. When the wind is blowing the right direction, I get a 21 kW station that's 150 miles away (but...don't expect that!)
In my area, there are no transmitters within 30 miles and nothing more than 100 kW within 70 miles. So interference and overloading are just not an issue, and this amp sings. I've got stacked Yagis, but frankly there's little point to that strategy as you lose much of the 3dB gain from the second antenna to the insertion loss of the balun that combines them. In contrast, this amp gives nearly 30 dB of gain -- that's 1000x the signal from a single antenna.
How reliable is the hardware? It's worked great for 24 hours ;-). If you're concerned about premature failure, run it inside your house (at the other end of the antenna cable's loss) rather than on the mast for the first 90 days. That way, you'll get a pleasant surprise of another 5 dB of gain when you move the amp to the mast where it should have been installed in the first place..
To anyone that may try to fix theirs: Be advised there are a number of open coils on the board opposite the solder side. These coils are professionally bent and spread apart (using professional diagnostic equipment) to give them specific characteristics (specific inductance). Do not bend ANY of these coils, or you will detune the circuit. Be careful not to touch them.
To Channel Master: Your Chinese assembly house is very sloppy. Bring it back home to the US, where people take pride in their work.
Update: I bought a new VHF antenna to try outside on the same mast as my UHF. I connected it to the 7778 I had out there and got fairly good results. Recently, I moved my unused 7777 to the roof top and bam, I can now, at night, pick up VHF channels from Toledo OH. I live about an hour and a half drive north (Lake Orion, MI). Just about all my local channels peg my signal strength meter, and are solid all the time. If you live close to the transmitters, an amplifier probably won't help you, but if you live at least 30 miles away from the transmitters, you can have amazing results with this amplifier... but don't skimp on your antenna. Would definitely recommend the 7777, just watch for the assembly issues in my review above.
Top reviews from other countries
I live in Calgary and less than 15 km from all the tv station towers just west of the city, but could not consistently receive Global or City tv signals which come from two towers side by side. Seemed odd to me as the other three signals (only 5 total available in YYC) were very good and their towers are less than 1 km from the others. I have a MOHU Sky antenna which is amplified but the amp just wasn't strong enough.
This ChannelMaster 7777 is sold as a high power amp and my concern was over amplification based on reviews. I used the Sky antenna (which is really compact and blends in nicely with my home exterior so I didn't want to use another one) and it immediately picked up the two stations super clearly. The other stations are fine as well - no apparent over amplification issues. I wish there were more OTA stations here in Calgary but now that I have the basics I'm a happy guy.
We have both strong and weak stations, and this amplifier adapts to both, not overdriving the TVs.
It's well constructed. I was also able to stretch the rubber boots over the connectors, and did not have to re-crimp connectors to get the benefit of this weather protection.
While you can get cheaper amplifiers, they probably won't work as well as this one. It's worth the higher cost.
