[Central-Electronics] 100V antenna relay

[Eugene Hertz]

Hi Jim et. al..

Thanks for the input. I have multiple receivers and plan to have 2-3 antennas.  I was wondering if it were feasible to hang several antenna relays off the 110V socket on the 100V so that I can disconnect several receivers from their antennas when I key the 100V.  Does anyone else do this? My concern with multiple dow relays would be a) too much current through the 100V (I think it has an internal relay) and b) too much noise closing 2-3 relays at once.

Does anyone know of a solid state coax relay that can handle 100W output?

Eugene
