[Premium-Rx] Multicoupler

[Bob Betts]

Hello Group:
I've built a few different designs, active and passive.
This one is simple to build, has good port-to-port isolation, unity gain with a MMIC preamp if necessary, attenuator, and good EMP/static discharge protection. I also incorporated direct/coupled switching just to allow comparisons with direct antenna connections.
