The Mini-Kits EME220-6M is a High Performance RX/TX masthead Pre-amplifier mounted in a Hammond 1590S enclosure, and is specifically designed for the 6m 50-54MHz Amateur Band. The design uses the Mini-Circuits PGA-103 E-PHEMT amplifier that has a very high dynamic range and ultra low noise figure, and provides superior performance to Mos or GaAs FETs. The gain is adjustable so that the gain distribution can be optimized for coaxial cable loss that can be significant on the 2m band, and also to suit the receiver gain.  The design incorporates VOX RF sensed changeover Relays for Trasnsceivers up to 100 Watts CW without using sequencing, or can handle up to 500 Watts PEP if sequencing is used.  An on board bias tee ( DC power injector ), allows the pre-amplifier to be antenna mounted and powered via the coaxial cable. A Tuned input T type filter and low pass filter provides high rejection of signals at 144 and 430MHz.
