Description Technical Specifications FAQ's & Support
The Channel Master television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This antenna amplifier 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.

• Combined VHF/UHF inputs
• Recommended for residential installations
• Gain: 30 dB, 54 to 860 MHz
• Includes a switchable FM trap
• Outdoor rated housing
• Mast mounted amplification unit with indoor power supply which connect via coaxial cable
• Preamplifier and its power supply can withstand up to 140° F temperatures

WARNING - The CM-7777 is recommended for professional installers only. This amplifier has a high gain output and can result in over amplification if not used in the appropriate scenario. Over amplification can cause issues with a television tuners ability to receive and display some or all channels. An ideal scenario for the CM-7777 is an application where ALL broadcasts towers are 60+ miles from the broadcaster and a splitter is used to distribute to multiple televisions. Just one high power signal or broadcaster that is close in proximity can cause over amplification resulting in the loss of reception. The CM-7777 is a high quality, high gain amplifier and is subject to misuse, less than 1% of the CM-7777's that are returned are actually defective.
Channel Master recommends the CM-7778 amplifier for consumers that do not have the ability to measure or calculate signal levels. In 98% of consumer applications, the CM-7778 is the best choice and will outperform every other professional grade amplifier on the market without having to worry about over driving strong signals.

General Preamplifier Information

The TV Antenna preamplifier is useful for persons unable to view channels due to weak signal. The preamplifier will boost the signal received by the antenna making it much stronger by the time it reaches your TV set.

The Channel Master preamplifier is a two part unit, an outdoor amplification unit which is mounted on the mast of your antenna system and an indoor unit which powers the outdoor amplification unit. The indoor unit is stationed indoors and connects to the outdoor unit via coaxial cable.

If you already have an antenna set up and are considering adding a preamplifier to boost your signal strength. You would only need two additional short length coaxial runs, one from the antenna output to the preamplifier input (which should be no more than 5 feet) and one from the indoor power-supply to your TV set. You would simply use the current longer coaxial run to connect from the mast mounted units output to the indoor units input.
