Hi, Richard, A bit of errata to correct my previous post: The difference in current will not be as large as I stated in my last post, because for the pair of 1/16 radials I did not divide the source current between the two 1/16 radials, and therefore the difference is not nearly as large. This

Topband: Radials

Moxon, G6XN once proposed using elevated radials that wereless than ¼ wavelength long, tied together and fed through a commoninductor.His idea was it would beeasier to achieve current and phase balance between the radials if they weren’tphysically resonant.I believe this waswritten up in one of

Hi, Carl, I repeat, a folded counterpoise is NO substitute for a dense and uniform system, which is what you had in the end. My question for you is if you had a 70 x 10 foot strip of that rocky stuff to construct a counterpoise, and that was all the space you had, period, and your neighbors

Tom,   I only have about 491 ft of window line and thats what I am using for the two direction beverage. Placement is in part dictated by the hill but mostly the rationalle for the 300 or so feet from the inverted L is that it has a lot of noise.  It is terrible actually much of which

You sort of lost me a day or so Guy as the posts were getting way too long and boring (-; that I deleted after the first page. It appears that the FCP sort of took over the radial discussion somewhere along the way when I was sleeping and the subject line changed.. How about we leave the FCP to

I haven't been following this thread real close, but I folded the two 10' high elevated 1/4λ radials on my own 3/8λ inverted-L --per Guy's suggestion to me a two or three years ago-- as follows: Radial # 1: North about half-way (a little less than 1/8λ), then east 10', then south the rest of the

I am curious why you specify #18 Teflon wire for the BOG wire you list about 1/2 way down the page. Black polyethylene insulated wire would hold up a lot better over time and would be far cheaper, so I'm curious if there is some specific reason you would specify Teflon? The only thing I can think

Ive had a single wire 600' BOG for a bit over a year and I must say Im impressed. Its partially on the ground and rises to 6-8 on ground hugging shrubs. It doesnt require a preamp, likely due to the poor ground here not bleeding off signal. Its quiet and less susceptible to crud from a
