[Elecraft] Antenna?

[Steve]

Mike (and others)...

There's been some discussions on the HFPack list about a ground independent
vertical design, published in the April 2004 issue of QST.  The author,
Brian Cake, KF2YN, describes a "C-Pole" loop antenna resembling an OCF
(off-center fed) horizontal antenna, only wrapped in a loop.  A tree branch
about 18' off the ground is all that's needed to hoist the 20M version into
the air.  Feed is at ground level through a choke balun.  EZNEC shows a low
angle of radiation, and no radials/counterpoise, etc. are needed.

Details for the 20M version may also be found:

And the original article describing the background and 20 - 10M designs:

HF verticals perform poorly without, as you mention above, a very good
counterpoise or ground plane.  In temporary portable installations, that is
generally very difficult to obtain.  But for a dipole, it's a non-issue
altogether.
