[CQ-Contest] Multi 2 locking device?

[john at kk9a.com]

One somewhat expensive solution is to use a triplexer and then feed each
bands coax into a 2x6 relay box such as a SixPak. The relay box makes it
physically impossible for both radios to connect on the same band. The
triplexer will allow you to operate on two bands simultaneously with using
the Cushcraft beam using band pass filters.

Hola,

I'm planning to operate M2 LP, the oncoming contest season.
I do have two WX0B passbands filters from my previous SO2R setup.

-Only two radios will be used.
and
- Very simple antennas setup on a city lot:
Log periodic Cushcraft ASL-2020
Vertical tribander Force13 VR-3
Twin Slopper Alpha-delta DX-A

Is there any summary related to options available for locking devices to
prevent two radios to operate in the same band?  I do not want to have burned
front ends.
Preferably,  I would like to build it.

I appreciate the feedback
