The HN is a tough connector. At my former employer we used to run close to 2.5 KW thru them into fairly reactive loads. This was in the 130-180 Mhz freq range. I don't remember ever seeing one fail.
73, Stew K3ND Because of a current/voltage node I was toasting SO-239's (FORGET Type "N"'s).... I went to Amphenol Type "HN" connectors in the 160 tuning box at the base of the tower. It NEVER arcs now, ever..... http://www.amphenolrf.com/products/hn.asp?N=0&sid=52AE42803C4E617F& They are not cheap, but they work great... 73, John, W4NU Stew and John, I have been using HN connevtors since the 70s. Someone gave me about 150 ft of new RG-17 and the local surplus store had a bunch of all types of HN connectors. I bought a few. If you use them, try to find the ones with the captive center pin. In the ARRLs article in the 60s on a pair of 3-400zs in GG, they used an HN connector for the 3kV B+ connector. 73, Price W0RI _________________ Topband Reflector Archives - http://www.contesting.com/_topband
