This low cost Receive Only 6M Pre-amplifier has been designed to be easy to construct and can be center frequency tuned for use between 45 and 65MHz, and is suitable for the 50-54MHz amateur band. The Pre-amplifier has the option of being powered via the coaxial cable, and is very suitable for retrofitting inside older transceivers to improve the weak signal gain. A low cost BF998 MesFET has been used as it has very good characteristics on the VHF to UHF bands. The BF988 was specifically designed for television tuners and has a low <1dB NF @ 800MHz, along with high cross modulation performance.
