Boy, that practically out of my dream book of LF antennas. If you use
the above points I'll be very interested on how the mechanics work out
to erecting it.

For the mast I'd reco the 3" pvc, it being less spaghetti-like, a
benefit on erection. Consider that a pvc plumbing flange can be used to
hold the center part of the top hat. However, I suggest setting the hat
on a separate and smaller mast that at raise-up time is inserted into
the main 3" pipe. With a 3-foot stub pipe, it should be self securing, I
think. This way working on the top hat will be separate from the longer
and clumsy mast. If done this way the down wire would be secured to the
mast also before raise-up.

I'm not sure what is meant by 6 gauge radials. Possibly they are rods.
Ok, then just connect the ends with several "halos," starting at the
outer ends. How many connector wires? Don't know the pay off, but must
have 1, more is better. I never built a non-wire top hat, so I'm going
by what I've read.

The use of weed-line sounds good. Bill A. once said that a loop-end
from it could be secured with a compressible tube of copper. (Tying it
in a knot is not known be me.)  I know the home stores have those for
wire rope. Never used 'em. If instead you have to use easier-to-tie
rope, consider using light pvc tubes, say, 1-foot long for insulators.
And as per BRO's vertical description, part of his "top hat" is in the
top guys, up to the first insulators. But this can't be carried too far.
:-)

Cheers on the project.
