Topband: RX antenna switching - unused ports

[Brad Denison <brad.denison@gmail.com>]

All,

  I am working a homebrew RX antenna switch box for my beverages, flags and
shared apex loop array and am looking for design advice.  Can someone
educate me on the proper way to handle unused ports:

1)  Leave all unused ports open
2)  Ground all unused ports
3)  Terminate unused ports to 75 ohm


I have seen various commercially available switch boxes with all of these
configurations but it is not clear to me if any of these variations are
best, i.e does it matter?

Thanks,

Brad, W1NT
