Interlocked switches should not be necessary for receive applications.
If by interlocked you're looking for a way to deselect one antenna
when selecting the next, check K1TTT's web site. Dave had a push
button controller that would release previously selected antennas
when making a new selection. I haven't looked for it recently so you
may need to do some digging.
