Topband: Video Switch for Low Band Antenna switching

[donovanf at starpower.net]

As an alternative, in my opinion the receiving antenna switching capabilities 
of the K9AY 8x2 switch are far superior to any available alternative: 



- eight antenna input ports 
- two independently controlled receiver output ports 
- any antenna input switchable to either or both receiver output ports with no interaction and excellent isolation 
- two, three or more antenna input ports can be simultaneously switched to either or both receiver output ports

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!
