I've been looking into this lately and I'm "almost" ready to start
an actual build. My basic plan is for an electronic switch box.
I have plenty of Omron (Ice Cube type) quad relays (12vdc)
My plan is to use the relays to break the shield as well as the
center conductor for each output. Each relay will have a pushbutton
switch and an LED. This box will NOT be used for multiple antennas,
but for 1 antenna and multiple radios.
The relays will be mounted on
a piece of DIN rail and isolated from the metal box and the bases
are plastic so there will be nothing common to all relays except for
the power to charge the relay. The SO239 connectors will have to
be mounted on a piece. of plexi or something non-conductive to keep
them isolated from each other or use shoulder washers.
The only thing Im not sure of is:
1)Will there be a coupling issue by using relays?
2)Will the relays introduce some RF?
3)Is there anything in my design that would create loss?
4)Can I use 14awg solid wire for connections or should I use short
pieces of coax to connect relays to the SO239's?
As always, I love this hobby and love having this forum
to vent, explore, and learn.
