Unusual to see that as an issue withought using an amplifier, however the high antenna feedpoint impedance on such setups produce a high voltage at that point, despite the atu proving a 50 ohm impedance match to the transceiver.
Baluns rated at 3-5 KW are so only at 1:1 swr. When swr raises to 5:1 on certail bands on a ocf setup then really you should derare the power rating by the denominator 5, such that a 5KW rating becomes 1KW. This will provide a long life on ocf setups etc. "Recently I had to dismantle my antenna (brand name unnecessary) to take out a burned gas discharge tube. I had been operating it on a Warc band for which it was not designed, made possible by the efficient tuner of my K3. I was told that the tube might have/probably burned out because it was seeing a high SWR that, of course, was not actually corrected at the antenna (just in my radio, as expected). Now, if that was what happened, what is there to keep the same thing from happening in my K3? Obviously, there must be something! 73, Scott XE1/AA0AA; AA0AA" -- View this message in context: http://elecraft.365791.n2.nabble.com/Antenna-static-charge-precautions-any-tips-tp7562287p7562349.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
