Much simpler solution, build 3 element quad with wide spaced elements and
you get 50 ohm impedance, good pattern/gain and simple antenna.

Well, there you go! I had it in the back of my head that adding appropriate
parasitics would pull the impedance down. My problem was that all I had to
fiddle with was the driven element and a reflector.

With apologies to Yuri, I may still try some of the stranger approaches --
simply to see what works and what doesn't.
(My approach to ham radio is like farmboys playing with dynamite, except you
don't usually kill nuthin'.)

There probably is not anything new to done with Quads but please share
your experiments with us!

Some things I discovered:
1- Quad made from copper pipe gets heavy fast.
2- It is possible to match the driven element with Gammas, hairpins &
such but not worth the bother.
3- If nothing breaks when a Quad is loaded with ice it will probably
be all right after the ice melts.
4- Maintenance will be required frequently.
5- Stealth Quads are especially hard to do.
6- Lighter and more flexible is more durable.
7- If your transmitter will tolerate it, it will radiate well off of
design frequency but the pattern will be difficult to anticipate.
8- Due to the radiator being a closed loop the receive noise will be
down from most antennas.
