Topband: Suggestion for RX Antenna control box/switching box

[Ray Benny]

I'm trying to figure out in my mind how to build a box that will allow me
to select a HiZ 4 square, two beverages, an RX loop, and switch in an MFJ
1026 Noise Cancelling device using the listed RX antennas - to two radios
using their external RX antenna jack. I know that I need to be concerned
with isolation and grounding. Can I use several older ceramic rotary
switches, relays or what?

How do some of you do it? Can you share a block diagram, a schematic and
maybe some construction notes?

I appreciate your input!
