[Antennas] Dipole Height

[D.J.J. Ring, Jr.]

Ken,

Either your work hours don't let you be home near sunset / sunrise or you
just don't go after DX on 40 meters, because judging from your QSO map, you
should be equalling your 10m performance on 40m as what you have there is a
legendary signal squirter of major proportions.  A 400 foot loop up 90 feet
should work VK and JA long path in the fall - this month and a few months
into Winter, easy over the North Pole DX to UA0 - they're not common, but
your antenna will compete with the big boys, believe me, I've been there
(I've been very far away from USA and listened and worked stations from
N1EA/MM on ship) and kept a log of what stations were always heard and the
guys with the 400 foot loops were always heard as were the dipoles up high
- but no one, no one, had a loop up 90 feet.  You would have made N3EA/K3JH
Joe Hertzberg's (SK) legendary 4 element 40m yagi at 60 feet sound like a
QRP rig.
He had a Big Bertha 120 foot mast, 2 el quad on 80, 3 el yagi 40, 6 el 20m,
5 el 15, 6 el 10m.  Plus 1 kW input full QSK, he ran RCA's Philly vacuum
tube plant.

I couldn't find a picture of K3JH's array but it was featured on the cover
of QST one month, but here's some antenna aluminum for the dB gallery.
