I would suggest, a good coax choke also. Cheap easy and good insurance. The real problem of the 9:1 un un is that IF the transformer is not balanced, there will be CMC to deal with.
Mel, K6KBE From: Dan Presley <n7...@arrl.net> To: K2 <elecraft@mailman.qth.net> Sent: Wednesday, February 8, 2017 4:14 PM Subject: [Elecraft] EFHW clarification Thanks for the replies so far. Just to clarify-I plan to use the built in auto tuners in my KX2 and 3, so hopefully they can handle the job. I already have a good 9:1 transformer which should work. The primary question is the advantage to the EFHW as opposed to a true random length (not a halfwave at desired freq) with a counterpoise. It sounds like the high current point is a quarter wave from the feedpoint which could be an advantage from the random length. I’ve also seen a variety of ideas on the proper length of coax to use with an EFHW, which as I understand will act as a counterpoise. I now have one of the nice lightweight SOTA poles which would be good with whatever wire I go with. Waiting for some decent weather in the Pacific NW :)) Dan Presley N7CQR n7...@arrl.net ______________________________________________________________ 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 Message delivered to farrerfo...@yahoo.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 Message delivered to arch...@mail-archive.com
