I am interested in remotely switching among multiple balanced lines (450
ohm). There are latching vacuum relays that I can use, but they cost
from $9 to $15 each and are mostly spst. I originally thought to use
two
relays per antenna, one spst on each side of the line.
I would like to know whether one can switch balanced lines the way one
might switch coaxial lines, by leaving one side common and switching
only the other side. This would, of course, mean that I would need only
half
the number of relays that I would need for switching both sides.
Thank you for any information.
