[Elecraft] KPA-1500 failing on 160...AGAIN!

[john at kk9a.com]

5000 watts is 500 volts rms with a perfect antenna system. I suspect  
that PL-259 connectors really can withstand much more than 500 volts.  
Has anyone tested them?  My station has a mixture of UHF, N and DIN  
connectors and all have worked perfectly for 1500 watts HF.  If  
PL-259s are failing they are either poor quality connectors or there  
are serious antenna issues causing excessive voltage.

 From the Amphenol data sheet, UHF connectors are rated for 500 V  
peak, so they are marginal for use at that power level. Type N  
connectors are rated at 1500 V peak.
