[Elecraft] Re:elevated radials

[Stuart Rohre]

I am not sure we are talking about identical radials, but certainly, the
gull wing elevation concept has been used multiple times by the Force 12
President, and tested with outstanding results.

L. B. Cebik has addressed the limits of various modeling programs, and
possibly has working models on the elevated case.
<cebik.com>  Cebik has modeled and stated that vertical DIPOLES are not
aided by radials, to any significant degree to justify their use.  Of
course, a half wave dipole vertical or horizontal is a complete antenna unto
itself.

What I thought about, how much different is the case of the base of the
vertical being on the ground level, and the gull wing radials above by a
couple feet or less until they slope down to the base of the main mast, and
feed point, and the case of elevating BOTH the main mast and the radials?
Was that what was modeled in 88?

Now, I would like to propose another solution to quarter wave antenna
completion.  Since radials laid on or in the ground have been shown to be
lossy, or often to not have the same current in each radial, (a condition
for them to not radiate), (QEX had the piece on measuring current in radials
on the ground), consider another method:

If, radials were buried in larger PVC conduits, such as to have some air
around each wire, and not be in electrical contact, or high capacitance
contact with dirt/rocks, would you improved current equality, and efficiency
of the radial?

Also, maybe it would be more appropriate to continue this on QRP-L rather
than a specialty reflector.  I think most elecraft reflector types get or
can get QRP-L or read the digest via QRP-ARCI web site.
