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

[Walter Underwood]

Few of us can guarantee dry air for our antenna connections. Where is this data from?

For the question “Has anyone tested them?”, I expect that Amphenol tests to the published specs. Those tests would be over the entire temperature range in the data sheet. If you visit the data sheets I linked for the UHF and type N connectors, you might notice that type N has spect for many more attributes than UHF.

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.
