Homemade Coax Switcher

This is a coax switcher unit I made out of some parts lying around in the junk box. What I have done is modified an old ‘100 Watt CB antenna matcher’ unit and added an extra SO238 and a double pole switch to be some functional I can now use with my 2m/70cm setup.

Parts break down:
Metal box 51x51x32mm from JayCars be ideal, or bigger for more sockets
3 x SO238 panel mount connectors
2mm silver plated copper wire
double pole switch
