The argument in support of using high elevated radials is not supported by the N6LF data.  In fact the data Rudy has says even a slight elevation from ground gets you most of the way there with respe

No idea.  In his article, you can infer on fig 17 that 4' on a 40m antenna is about 0.06 WL.  And going from 0.5 to 4' was worth about 3/4+ of dB.  Is there a reason to think that height above ground

Dave, There are a number of articles that reference non-1/4 WL radials and the benefits.  That made complete  sense to me and the verts and 4sq that I built were made purposely with lengths not on qu

After getting my hands on a floating 80m vertical one summer and then getting up off the ground, I decided then and there that the 50K 200W resistor in my junk box could do some good and maybe save m

Apples and oranges. Hose clamps work fine with HORIZONTAL elements.  The slightest compression is adequate to contain most movement. But the issue K3PA mentions is with a vertical 4SQ.  That is a com

I could not remember what a DB224 was.  Looked it up and was laughing to see the hose clamp on that antenna.  The funny part is that in the current version, they have doubled up on the hose clamps -

John, I built a 30/17 dual monoband using AutoEZ for the optimization.  The result has been excellent and AutoEZ makes the various compromise/optimization considerations manageable.  If you enjoy tha

At Dayton/Xenia antenna forum this year 2022, N9NB had a pretty interesting talk on low band verticals.  The key take-away from that was that you could reasonably determine your actual ground loss ba
