Jeff,
Considering practical construction as well as radiation performance...
2-element wire beams are hard to beat. They are very forgiving on
construction -- you'll get an honest 3 dB gain even if they're mis-tuned!
They are much easier to put up than 3 elements -- less than half the boom
length and only two elements to line up. Point one about 020 deg. and the
other at 300 deg. Build the 300 deg. one first, since it will give you the
most benefit. A dipole broadside NNE/SSW will cover W8 through W1 if you run
out of time to build two beams.
I think you'll be disapppointed with half-squares or bobtails. I've never
seen them perform very well. We used a 40M bobtail for FD in Colorado for
several years, but one year put up a wire beam, too -- beat the bobtail 95%
of the time.
The phased verticals are not a bad choice. In 1986-87, I had two elevated
40M ground planes (feedpoints up 30 ft.) spaced just under 1/2 wave. They
worked very well, just one small step below the locals with the typical
shorty forty at 75 or 80 ft.
Be sure to have a decent antenna for 80, too -- 40 will probably go long
early.
Good luck -- I'll be operating portable from the new QTH construction site
with a few wires in the trees.
Go SMC! (Unlimited)
Go SECC! (Medium)
