Joe and all,
That is my favorite portable antenna too. In a pinch you don't need 3
supports, 1 will do to hold up the center. The 2 antenna wires and the
feedline CAN also be used as part of the guys to hold the center pole
upright and you have an inverted VEE - OR with one half of the antenna
positioned along the pole you create a vertical (leave the excess wire at
the top dangle or tie a line to it to make sort of like an inverted L - the
higher current is at the bottom anyway) then run the other side along the
ground as a radial - yes in this vertical case it would be good to have
another length of 23 foot wire to add as a second radial running in the
opposite direction from the first to cancel the high angle radiation -
better low angle radiation if you are searching for DX rather than locals.

This is basically a center fed ZEPP. When I was at T30NN and 3D2NN I used a
center fed ZEPP which consisted of a 44 foot piece of 300 ohm TV lead-in for
the feed line and the horizontal parts were stranded #18 wire each side
being 23 feet. Using the K2/100 and KAT100 this antenna tuned 80m-10m with
1.0-1 vswr. The antenna center height was at 17 feet, supported by a fiber
glass extending twist/lock pole from SteppIR antennas. Each end was held up
by a 15 foot fiber glass extending twist/lock fishing pole from Walmart.
See, sometimes when on a remote place there are no trees to support an
antenna, so you carry your own fiberglass poles. I worked many, many
stateside and EU stations with this portable antenna.
