The antenna shown uses fiberglass tent poles. They are 2ft each. The
larger version uses fiberglass rods from Tap Plastics. They are cut
to
fit the back of my suv, something like 65 inches. I'd love to use
the
antenna with the amount of wire indicated on the Wellbrook site.

I suspect someone could roll their own Wellbrook. I believe they use
a
very wideband transformer and a low noise JFET amplifier. You can
find
wideband transformers on ebay (North Hills). JFET amps aren't that
hard
to build. The transformer lets you float the loop and does the
double
to single ended conversion.

The Wellbrook is definitely a balanced amp, but I've not
heard of someone who's either reverse engineered it or
built an approximation of one, as the demand would be
pretty good, I'd imagine.
