I can't comment on the folded counterpoise because I am not familiar with it. The "broadcast model" which I take to mean 120 radials is used because in the case of a 90 degree tower on medium wave, t

Hi Rob I see copper prices have doubled in the last year. https://k2av.com/Olinger_NCJ_article_on_FCP.pdf he says "The reason for the FCP is twofold: minimal space and a low-loss alternative to radia

I see copper prices have doubled in the last year. This is a false dichotomy between FCP and a broadcast station ground screen. The best use of wire is to have a small number of elevated tuned radial

Thanks, Rick. My particular circumstances limit me to a small triangle of ground in the corner of a field and the FCP suits that very well. It would be interesting to know how the FCP compares to som

electric fence wire works perfectly for elevated radials  Also consider N6BT's single spiral radial configuration as an alternative to FCP. Rick N6RK _________________ See: https://nextgenerationante

I took my inspiration for the one turn counterpoise idea from HF Antenna For All Locations page 155, Fig 11.9(m). David G3UNA _________________ Searchable Archives: http://www.contesting.com/_topband

N6BTs ring is pretty flexible in its dimensions. It can be 3 or 4 sides (or anywhere in between) and can handle some variation in symmetry. Ive been having issues finding a solution to the high tree

As usual, I agree with Rick. But I'd like to observe that an extensive study of loaded mobile whips published in two parts in QEX about ten years ago showed that inductive loading, especially at the

According to Roy Lewallens Eznec site there are no more expensive versions of his Eznec software. He is retiring and is leaving a last version for free download. Take a look at Eznec.com for details.

73, Jim K9YC I wasn't clear. I assumed that the vertical has top loading wires, and the base loading inductor is added to get resonance. According to W8JI, once you have enough top loading to get un
