But for what he originally wanted as far as covering two parts of 80m,
with one antenna, I still would prefer paralleled dipoles, cut for
each section of the band. I would run them at right angles like a
turnstile. The SWR curve will look like a "W". Solves his problem, and
is still ultra efficient with no caps to diddle, weird feedline
combos' etc..Add 40m legs, also in parallel, and it's instant
bandchange between both parts of 80, and also 40. Won't have to do a
thing except dial the radio around...I think he said he's already got
the high bands covered...To me, thats the "perfect" antenna for his
problem, and what I would run in his case. But to each his own I
guess...


Mark as usual one size does not fit all. Particularly when antennas in
small back yards with limited antenna support options come into play.
Which is what I'm dealing with. If I had enough real estate available
to put up crossed coax-fed dipoles/vees I'd probably do that. But as I
pointed out earlier I don't have enough real estate, not even close.
So your solution is irrelevant here.

The jumper-to-bandswitch antenna would work IF one was (a) able to
drop and hoist the antenna quickly and conveniently (b) was inclined
to futz around in the dark to change bands. Which I'm not. I've
installed dipoles at this site before, the trees I use for supports
are gnarly beasts, simply dragging one insulator per end per weekend
thru the things is a major hassle. There are still a couple end
inulators dangling in 'em from previous (broken) antennas so that
elimimintes the quick up/down idea and hauling multiple insulators
and/or traps thru 'em.

I *might* have 20 & 15 covered *if* that antenna works. But I don't
know yet one way or the other so I'm still planning on an
off-the-shelf G5RV to cover my butt this time around unless a better
idea come up. I've used G5RVs before, they're far from my favorite
type antenna mostly because of the need for a wide-range ATU but they
do work and are applicable to a much wider range of installation
conditions and restrictions than any other type of coax-fed multiband
HF antenna that I know about.
