Thanks Cecil. It probably is a power-sink when xmit. The antenna was
originally set up as a receive-only antenna, and you should hear the
difference in volume when the grounded side of the Balun is off/on the
ground rod. Audible increase (for DX purposes, where a couple of S-units
is
a lot, hi). I'll try the radials, and disconnect the shorting ground, and
see if this improves things a little. I never heard anyone mention
making a
"vee" dipole antenna (from the ground-up), is that a NVIS?

I would think it would be NVIS. A lazy Vee ( horizontal wires) is
directional going from the point through the midpoint between the two
ends.
If it is directional horizontal, it must be directional pointed strait
up.

Adding a single radial under 45 degree random wires did not have a
noticeable effect on 2182 performance under the midday sun. 100 miles was
it's maximum and barely readable (both ways) from the one station I talked
to. Even if I did configure it for NVIS, that would make a totally useless
daytime antenna for MF, with all of it's energy being absorbed. The
Canadian stations certainly do well, being loud and clear from Halifax, St
Johns, Placentia, Labrador, St Anthony, all the way to the Mid-Atlantic. I
guess a vertical or high elevation 1/2 wave dipole are the only solutions
for daytime success there. Maybe a job for the super-Isotron, hi, hi. But
seriously, I might try a much longer wire, something close to 1/2 wave, with
a feedpoint-choke but no Balun.
