It appears that the better video switches need a signal from the vertical
blanking interval to switch. No
signal, no switching. Probably explains why they are so cheap on eBay!
I have 3 bi-directional Beverages, an 8 circle and 4 square receiving antennas.
I would like to switch
any one to my K3 main rx, K3 aux rx, R-388 or DX Engineering NCC-1 phasing box.
That's 8 inputs
and 4 outputs minimum.
Ideally, some sort of matrix arrangement would do. I've looked far and wide for
a commercial unit that
would do the job but no luck. Virtually everything is designed for SO2R
operation. At present, I'm using
a switcher used in RV units. It has 5 inputs and 3 outputs. I use a separate
switch for Beverage selection.
Thanks for all the inputs!

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!
