I've used dozens of $2 PC board power relays over the years in various
antenna switching applications, and have never had a failure at >1300
watts and SWRs from 1:1 up to over 3:1. W2VJN reported similar, much
more rigorously tested results at TopTen Devices. I don't see any
reason to gild this lily further.
