Instead of a quad I built a delta loop version which required only two
aluminum spreaders per element and a connecting wire on top for each
element. Every V spreader was attached to the boom with conventional
"U" clamps and the driven element was gamma matched. I haven't seen
such a design written up since the 60's for reasons unknown. The
antenna was only 6 elements but worked well. I had wanted to get as
much top loading as possible for my tower as it was shunt fed on 160
meters, something that fiberglass spreaders won't do.

Quads are a pita. 4 x spreaders per ele, and
some form of spider to mech connect all the spreaders..then onto the boom.
