I have a coax-fed multiband dipole (for 40m and up) swung over a 80 ft
Platanus acerifolia (what a luck !).
For 80m and top band, I use a switch (found in "Hints an kinks" many years
ago) to make it a "LW".
My shack is upstairs, and I don't want to use the poor AC ground for many
reasons.
So I need a counterpoise (maybe I'm wrong). It will be short and T shaped
to minimize radiation, as shown in Moxon's book (that's my bible).
In a previous location I had successfully tuned an upstairs ground lead
for top band : it was very pleasant to see the antenna current increase
(with a home made RF-peg) as I tuned out the gnd wire reactance.
For now I have not enough spare time to DIY (although I assembled the K2,
hi). Had a think about Ten-Tec artificial ground, but it's difficult to
find here, and now I fully appreciate the auto gearbox of the K2.
Then T1 appears : if it searchs for a current maximum, that should work,
why not ?
So, is it possible to use it as a counterpoise-only tuner ? (KAT2 does the
rest)
