Masthead pre-amp for 23cm using G8FEK LNA

March 2, 2018 No Comments

In April 2017 I constructed a masthead pre-amplifier unit for 23cm ATV (Amateur Television) using a G8FEK low noise amplifier (LNA), two Tohtsu CX-520D coaxial relays and a homebrew PCB.

This video gives a brief overview of how I have constructed the unit and I describe how it works.

See the video for details for construction details.
