Antenna Matrix using many Koax-Switches:

I use Yagi antennas as well as a X-200 for 144 and 430 MHz bands.

Three transceivers can be connected to these antennas, two mobile radios and one FT-736. Additionally these transceivers can be switched as crossband-repeaters. This results in many possible configurations how to connect antennas to radios.

I was tired of continously removing and mounting antenna connectors, so I build a solution using antenna switches. This is not so easy since koax cables required an optimised circuit for best performance.

Here is a picture of my solution. Using these 8 switches I can select any combination of radios and transceivers I need:

and the complete system:
