RF Preamplifier

Mini-Kits produce a number of low noise Receive Pre-amplifier Kits for Ham Radio applications that are suitable for improving the reception of weak signals. Our masthead amplifiers are suitable for use directly on most Transceivers, and has an on board RF VOX circuit that detects RF from the Transmitter to drop out the relays to bypass the Pre-amplifier.  Most Pre-amplifiers have the ability to feed DC power up the coaxial cable to power the Pre-amplifier directly, and can be used on Icom multimode VHF/UHF Transceivers including the IC275/475/1275, IC910, and IC9100.   Alternatively a bias tee can be used to feed power up the coaxial cable for other brands of Transceivers including the Kenwood TS2000 and Yaesu.
