Tam,
The description was for the coil.
The total antenna is about 15 feet base to tip. The coil is about 1/3 of
the way up. The base is about 3 feet off the ground so the tip would be
about 18 feet up.

Frank,
The coil measures about 60 uH. The antenna is elevated about 3 feet on a
short tripod. The radials angle down the tripod legs and then out.
The coil is about 4 inchs in diameter, number 12, wound on a fiberglass
form. It is centerloaded. I am looking at it accross the yard, it is
about 6 inches long. It is would with about a point .5 pitch.
Calculations for a 1:1 pitch predict a Q of about 450.
Thanks,
Dan
Maybe I missed something, but how high is the TOP of the antenna. I.E.
How long is the whip? Is the loading coil at the base, or partway up the
antenna?

Dan,
Over perfect ground, I get an impedance of about 2.4 Ohms, with resonance
very close to 3.8 MHz. What is the tallest tree in your yard?
