M0NWK - Masthead pre-amplifier for 23cm

In April 2017, I built a masthead pre-amplifier unit for 23cm ATV (Amateur Television) using a G8FEK low noise amplifier, two Tohtsu CX-520D coaxial relays and a homebrew PCB.
This video gives a brief overview of how I have constructed the unit and the principle of how it works.
What does M0NWK mean? I'm an amateur radio operator and this is my callsign.
