Rich said: >The measured breakdown potential of a SB-220 bandswitch is c. 4900v at sea-level. At 390v peak output into 50-ohms, the actual potential across open bandswitch contacts is c. 2600v-pk.< And what is the manufacturer's rating? For some reason I don't understand, things seem to break down more readily with RF than with DC. 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
