[Elecraft] HF Verticals?

With the Hexbeam, which as I understand is a varient of the Moxon Rectangle,
or the VK2BQW, you have a potential low angle radiator with gain, and front
to back ratio. No reason to add vertical, unless Hex does not live up to
its billing. The vertical would not have gain, unless, (and you could)
phase two verticals. Make one a director, and lightweight material, and
walk it around to various locations supporting it with a T fence post and
short mast, (elevating the fed vertical), and ergo a vertical beam.
Why not just make a dipole for the 70 foot space, and mount it below (or
beside), the Windom a few feet, and droop both ends, so it can be closer to
full length half wave dipole for 80m? It will also load on 160 m with low
loss if fed with 450 ohm ladder line. A dipole can be shortened to 60 per
cent and still work with nearly full efficiency. Transmatch can make it
work on lowest band. That way, you could get 110 foot dipole in 70 foot
length. A full size 80m is only about 130 foot. Make it of no. 14 solid
pvc insulated wire from Home Depot.
Please let us know how the Hexbeam works re DX.
