[Elecraft] EFHW clarification

[Mel Farrer]

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.

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  :))
