I suspect it is effecting the

some way.
Ditto...But I don't know how long the vertical is. Being you need
loading, I'll assume it's shorter than a quarter wave...
Hi Mark,
Yes, its vertical height is 23 ft. It is elevated
6' above ground with elevated horizontal radials.
The input Z at the junction of the radials and DE
is 50 ohm j0 with no matching system. There is
a current un-un at the feedpoint, thus no
common-mode, and the Tx line is 1wl electrical.
The experiments with this type of loading was
begun around '95 - '96, and this vertical antenna
was erected in '98. It has been through near I/2
solar cycle, and all seasons. Time has a way of
dispelling illusions, and don't think for a moment
that I ignored the "loss" question.
To me, low far field noise
Do not assume all noise is the same or
that all originates in the 'far field' as EM
particle-waves.
