The Channel Master television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This antenna 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 works best for persons in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal use the Winegard AP 8700 and in very strong signal areas use the Winegard HDP 269. Preamplifier's are also used if you anticipate distributing your signal with a digital splitter to multiple outlets throughout your house as splitters reduce the signal strength available at each output.

• Combined VHF/UHF inputs
• Gain: 30 dB, 54 to 1002 MHz
• Includes a switchable FM trap
• Outdoor rated housing
• Mast mounted amplification unit with indoor power supply which connects via coaxial cable
• Preamplifier and its power supply can withstand up to 140° F temperatures

The most important element of a TV antenna system is the antenna and a close second is the signal distribution system including signal boosters.

Denny - Your TV antenna mast mount pre-amplifiers --- How are preamplifier's powered ? --- I don't see any easy way to get 120VAC up to an antenna if they are AC powered.
Paul, TV antenna Preamplifier's are two part units. The mast mounted preamplifier and the indoor power injector. The power injector is located indoors and requires an electrical outlet. The coax cable down lead from the mast mounted preamplifier feeds into and out of the indoor power injector. The power injector converts the 120V electricity to low voltage DC inserts it into the coax cable and sends it up the cable to supply the preamplifier operating power.
The answer is, the mast mounted preamplifier receives its power via the coax cable from the indoor power injector. Signal splitters should not be installed in line between the mast mounted preamplifier and the power injector unless voltage blocks are in use.. Proper preamplifier installation is crucial but quite simple.
