Topband: RBOG through radial field

Beverages don't work well over continuous wire fencing, salt water, or
other high conductivity platforms. If radial wires are perpendicular to
the RBOG there is less affect. Modeling I've done shows insulating 3
strands of 1800' barb wire fencing into 200' segments only under 600'
of #16 at 10' works ok as a directional Beverage, at 1.8MHz average gain
-19.6 dbi, forward gain at 30 deg elevation of -8.2 dbi or an RDF of
11.2 as calculated with EZNEC Pro/4.
I proved continuous fencing under worked poorly (very low F/B) with two
Beverages I built as bidirectional (2 feedlines) single RG6 before more
knowledge stuck to me, but sold the ranch before insulating the
fencing. What W8JI has to say is worth reading IMO,
