Unless you are hot switching, vacuum relays are definitely not necessary. 
Open frame relays work fine and they even seem to tolerate lightning strikes 
at my station.

I am looking into build a panel that would distribute 8 to 10 antennae to 5 
to 6 stations in a any-to-any setup to handle 1kw. Prefer lockout( if a 
sophisticated design), but even manual switching would
 be sufficient. I know it needs vaccum relays etc.

Don't want to reinvent the wheel. Where can i find a good design/precedent ?
