Features

  • Improves Signal Quality, Decreases Pixilation and May Increase Number of Channels
  • High Gain Amplification (26 dB) with Ultra Low Noise
  • Selectable FM Signal Pass-Through, Heavy-Duty Housing with Rubber Weather Seal to Protect Against Moisture
  • RF Shielding to Protect Against Interference
  • IMPORTANT: Because of the High Gain Output, the CM-7777V3 is Recommended for Applications Where ALL Broadcast Towers are 80+ Miles Away. Just One High Power Signal or Broadcaster in Close Proximity Can Cause Over-Amplification, Which Can Result in the Loss of Reception. For 98% of (Short Range) Consumer Applications, the CM-7778V3 Medium Gain Preamplifier is Recommended. Please Note: Kindly refer the Instructional Video and User Manual Before Use Which is Highly Essential

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.

Did not over amplify in week tv signal area. Great for long cable runs. UPDATE: Tried again. Testing San Diego. No signal and no light on on plug thing. Kept trying different wires. RG 6, RG 11. Discovered I had in and out backward on the preamp on mask. Planning on trying for a vhf station I want at 90 miles on channel 13. Antenna guy pa got channel 13 on this antenna and not 2 others. Long range. I'm supposed to get a channel 4 from L.A. at 90 miles. Everything from San Diego is listed as weak. Mexico comes in great. T.J. OT: My brother tried very old Channel Master indoor amp that was his father in laws. Owned electric store. Says channel 2-82. Not 69. Worked great. Did not need his vhf antenna anymore. ... show more

    • BEFORE you read any of the 1-star reviews...
I read them all, and they fall into two categories: premature hardware failure, and RTFM/mis-application issues. I just bought and installed one of these amps, and I'm focused on the second issue here. 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.. ... show more

    • Works great, but...
I purchased this amplifier (CM 7777) for the VHF antenna I have in my attic. When I first connected it, it worked great, but then, like a few other reviews, it died after just an hour or so of operation. Thinking Channel Master is a good brand with a good design, I thought it might be something simple like a cracked solder joint. I took it to work and examined it under our magnifier. I'm sure the design is very good, because when it works, it works well. The problem is the care used in assembly. Most of the solder joints looked good, but I found numerous splatterings of loose solder on the board. It looked like the floor after a plumber has been soldering copper pipe. Some were along side of components. I saw solder splatters across a transistor, a capacitor, and from a resistor to ground. There were also many other splatters that were benign. Also, the circuit board still had flux on it where the assembler manually soldered on the coax connectors. After removing the solder spatters and cleaning the flux off the board, I brought it home and hooked it back up. It's working now. Makes me wonder what the inside of the power supply looks like. Also, I have a 7778 connected to my roof-top UHF antenna. I wonder what that one looks like inside too... although that one has worked from day 1. 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. ... show more
