I think the 20 meter "Hex-Beam" has a 9.4 ft turning radius, so it
stands to reason that a 40 meter version could (with a little tweaking)
be made to fit inside an 18ft circle. In fact if you go to the "Traffie
Technology" specs page you see what looks to be an incomplete entry for
a 40 meter monoband version presumably with a 19ft turning radius and
weighing 40 lbs:

OptiBeam OB2-40M is probably the smallest 40m beam and the turning radius is
6m (19' 8"). Their OB1-40 dipole has a 7.35m radius. I am surprised that
your Force12 dipole is that small. Is there a problem with having an
antenna hang over your neighbor's property? Nearly all of my beams in Aruba
hung over the neighbor's property when turned a certain way. It really was
not that noticeable and it never caused a complaint.

Hey Gang
OK - here is a question - anyone out there doing custom beams? I have kind
of
a sticky
Right now I'm running a Force 12 D-140, frankly because that all that will
FIT
- I have a 38ft piece of property, and it has an 18 ft turning radius
I'd LOVE to have a bit more gain, but even the smallest shorty 40s I've
found
are SLIGHTLY too big.
I was wondering if anyone could design a 18.5 ft or less turning radius 40m
beam...
