Roger, as long as the switch is passive and not active it will work
well for you as unused ports are terminate in 75 ohms. I use a 12X1
Dynairs here and they have excellent isolation plus it terminates the
unused reversible Beverage feedline (which is recommended for greater
rejection). I just cut the RG6 minus the VF to multiples of a half wave
length so the termination at the switch appears on the unused port. I
prefer this to running voltage out to relays which always seem to fail
at some point.

I've been looking for a way to switch multiple receiving antennas to
multiple receivers. I know some hams are
using video switchers but info on them is scarce. There is a Dynair
SVA-100B for sale on eBay but no real description
of it's functions.
It seems obvious that you can, for instance, switch input 3 to output
7 but can you simultaneously switch input
5 to output 6? In other words, can you have more than one path through
the switcher?
Any other ideas on switching greatly appreciated!
73, Roger
