I've often thought of giving the crossed dipoles (I guess you call it a
turnstile antenna) a try on 75M since a 2 element yagi or quad there
might be a bit unwieldy :O

I've used turnstiles on 75m off and on for quite a few years. If you
are looking for gain over a dipole, don't bother. You won't see it.
You will only have the gain of a dipole when fed in phase, or 180
degrees out. "Changes direction".
The gain when fed 90 degrees out will be less than a dipole, being the
pattern becomes nearly omnidirectional. Don't let this totally scare
you away though..
Myself, I think the turnstile is one of the best NVIS antennas you can
use on the lower hf bands. If you want gain over a dipole, run them
parallel, and change phase. You'll see more gain over a dipole, if
thats what you want. MK
