The board was designed to suit the construction of receive only preamplifiers for the 30 to 500MHz bands. All Kits use the low cost BF998 MesFET from NXP has a low noise figure and were designed for television tuners.

With 18db gain and noise figure of 0.6db will give good low signal improvement to weak signals.

This will be mounted in water proof box just under the coax feed point of the RX Antenna, and is powered up the coax, from the Tait Transceiver.
