I'm trying out some of these in a QRO remote antenna switching application SPST, so far so good. What is different in the (clever) design is the coil isolation is 5KV. The contacts are rated for enough amps and volts for what I needed (8a 300v). The RF path is extremely short and has redundant pins. Less than $3 ea.

I would appreciate recommendations for general purpose SPDT relays that can
be used reliably for RF antenna switching duty - it is not a hot switching
application.  I am aware that the DC & 60hz AC ratings are not necessarily
indicative of RF performance..  any experience out there?

Thanks in advance.
