Another couple of questions relative to relays this time.
Some of my antenna relays have protective diodes and some don't. If a power supply were to be used only for switching relays, could the protective diode be placed at the output of the power supply, rather than at the relay?
Also, looking at a couple of Amphenol coax relays I have here, there is not only a protective diode, but a (very) small disc ceramic capacitor across the coil.
