Don,
FWIW:
Over the last thirty years, I have constructed about 18 beverages of
various configurations at three different QTH's. A lot of them were not
worth the effort to put together. It may be coincidence, but not one
beverage I used radial grounds on ever worked right. The QTH that required
radials was on solid rock with a thin layer of decomposed granite on top.
Rods in the ground were not only a joke, they were impossible. The terrain
was also very rough with over 40 foot of irregualrities due to dry washes
and outcropings.
At the present QTH, my soil is very conductive and wet most of the time due
to flood irrigation. A 1/4 inch diameter brass rod driven two feet into the
earth provides a nearly perfect beverage ground as best I can measure.
If grounds are a problem, I might suggest an array of two flags or
pennants. It works about as well as a 550 foot beverage, takes up a lot
less real estate, and doesn't require any grounds at all.
Good luck,
Larry - W7IUV
