To see the RBN, go to http://reversebeacon.net/srch.php
Type in N3ND, hit enter. Look for the 160m spots around 03z 15 Nov.
The 03z spots are at 400 watts. The 00z spots were at 100 watts,
before the band was really open to the SE. RBN's from two other
stations in the area were down by similar measure at 00z and up at
03z.
This is an up 70, over 60, down 5 wire fed via a feedline isolation
transformer against a 5/16 wave single wire folded counterpoise at 8
feet. No radials.
There is no way his small lot property could support a dense radial
field, either buried or elevated. Therefore, presuming that undense
irregular radials that would fit would be excessively lossy, per RBN
data previously gathered, the +33, -33 foot linear folded counterpoise
(FCP) is used instead, elevated at 8 feet. The folds in the
counterpoise are designed to self-cancel fields as much as possible,
thereby minimizing ground induction, which is loss to skywave. The 66
foot straight line (more or less, not critical) FCP footprint is much
easier to place on property than some miscellaneous attempt at a
broadcast standard radial field.
