Steve, I don't recall whether you ever mentioned what the length is of your coil. Is it an appreciable fraction of the overall antenna height? Also, I seem to recollect that some of the discussion in

I might add, the W0KPH site shows what appear to be electrically short loaded vertical dipoles, which have nothing to do with the claimed principle of operation of the EH antenna, so far as I can see

Yes. It is not my idea. I got it from the Lowfer mail reflector a week or two ago. I think Les Rayburn, N1LF, "invented" it but I am not sure. > Hi, Johan. Just for sake of historical accuracy, it w
Thanks for the clarification, Larry. That's most enlightening. I must say, I hadn't thought of the PL application for the 1000Hz tone. Last time I had any contact with such a network was a quarter ce
