The AP-8275 is a mast mounted pre-amp that delivers high VHF (29dB) and UHF (28dB) gain with low noise. 75 ohm input and output. Features a selectable FM Trap. This amplifer helps to make up for line loss and insertion loss
Chromstar 2000 Series Antenna Pre-Amplifiers
Features 75 ohm input for convenience and easier installation. Universal housing can be used with any off-air TV antenna. Made of high impact ABS material, mast mounted for easy installation. Flexible polyethylene boot covers on 75 ohm. Zinc-plated steel hardware; all mounting hardware included.
Selectable FM trap reduces FM signals (88-108 MHz) -15 dB to prevent overload, tunable FM trap reduces a 3 MHz band width by -12 dB. Both adjustable — switchable without opening the housing.
Transistor burn-out virtually eliminated with specialized circuitry featuring fast recovery diode that protects against lightning-caused pulses. Operating temperatures -40° to +140° F. 117 VAC UL and CSA approved power supply is included. (Does not include F-connectors.)
NOTE: Preamplifiers and/or amplifiers only amplify the signal your antenna receives. They cannot extend the receiving range of an antenna or help pull in signal. Also, DO NOT use the higher gain models within 35 miles of your transmitters.
