I am ONE of the people who claim that four elevated radials can have approximately the same efficiency as 120 buried quarter wavelength radials. I have installed such systems at three Standard Broadc
(an inordinately long post -- and well worth it!) William-- MANY THANKS FOR YOUR POST I have been making this same claim for years, with a few caveats, such as the elevated radials must not be too cl
Hi Bill, I strongly disagree that the early tests and articles meant very much. First, they deluded Hams into thinking 120 radials are needed to achieve maximum efficiency in an array. The truth is t
....but not a single A-B FS measurement to back up the claims. There is equal or even more emotional data the other way. Ask anyone who went from a few radials to a big system how they "feel" about
W5UN did extensive A-B measurements between a collocated elevated radial system and an extensive, ground-mounted radial system. And Dave chose the elevated radial system for his 4-squares on 80 and
-- -- Bill and John, I have constructed three of the TX antennas for 160 Meters which have been very similar to your description. I call them elevated Ground Planes. N5IA has a full quarterwave of Ro
Then that would be the very first actual A B field strength test, if made in a clear area free of other ground influences like old ground systems, that has ever been made besides the one at WVNJ and
All three of these systems raise the base and elevated radials to a point at which they can be considered somewhat independent of the earth. The behavior is expected and consistent with the work done
Gents: I've read this who thread and have to say that I think there are two points of view that both deserve due consideration. The first is the viewpoint of intense scientific measurement, the secon
Aside from efficiency, I've always seen far more re-radiated noise from elevated ground planes impacting weak signals on receive. With a balanced, symetrical ground plane that theoretically shouldn't
Yes, happened here with two elevated radials and had to de-tune the system on receive. I am currently using a single elevated radial and still have to de-tune that during receive. 73, Mike WA5POK ___
