The Amphenol 83-1SP connector that many of us use is rated at 1000 volts RMS, That well exceeds the voltage that most amateur 1500 watt amplifiers can safely produce without much more severe internal damage to the amplifier.

The vast majority of HF stations with big power amps use UHF connectors throughout, and are without such problems as long as quality connectors are properly installed. The only problems I've ever had with connectors were the result the connectors being junk quality, and it hasn't been voltage breakdown. Rather I've had them fall apart, and I've had the center conductor melt. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
