While ago I bought a low noise amplifier kit from Jim at www.w6pql.com. I’m going to try the LNA for FPV purpose on the receivers side between the antenna and the tuner module.
The LNA is set to work in the L- and S-band between 900MHz and 1300MHz. Althought it’s possible to configure the LNA for use in 13cm band (2.4Ghz) as well. See Jim’s page for details.
Some pictures and a gain plot:
Gain is ~15dB @ 1200MHz.
