Thom,
Sorry for the delay in reply. I'm catching up on a bunch of email from
several email lists...
The author advocates using a 1/4 wave (less 5%) as a counterpoise for this
antenna.
I agree: this does sound a lot like the W3EDP antenna, which is described
in "Practical Wire Antennas", pg 33 (among other places). In this
reference, the W3EDP antenna is described as an 85' radiator and 17'
counterpoise. Connect both wires at the back of your tuner.
I hope this helps,
Steve
