This low cost Receive Only VHF 2M Preamplifier has been designed to be easy to construct and can be center frequency tuned for use between 115 and 180MHz. The Preamplifier is suitable for the 144-148MHz amateur band, and also for weather satellite reception on 137MHz. The Preamplifier 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 0.7dB NF @ 145MHz, along with high cross modulation performance.
