Beware of making broad statements that are supposed to be true in all
cases. The one above is not.

Bill, W6WRT


One statement that IS True, and has been around "Forever":

Ground is not Ground, the World Around........


Me and RF Ground, is not Ground Ground........


As was pointed out before and mentioned by someone else, if the antenna
is mounted so as to be fed by a feed-line running at ground level AND
fed at this low point (coax probably best in such close proximity to
"ground ground")--and a set of rf grounding radials emanate in all
directions from this feed point (but just below ground), BOTH EARTH
GROUND and RF GROUND are at or "are very near" exact points.

For most other situations which come to mind, your statement is true.
