John:

Andrew Corp. made a good living back in the dark ages (40s-60s)
manufacturing and selling 50 ohm folded monopoles. I can go measure the
element diameters on mine if you are interested. If I can recall where

it
is stored. It uses a small inductance at the feed point for matching.

Thanks, George, but the inductor at the feed point is disqualified. The

idea
was to learn if everything could be done by just clever design. It appears
not.

But, thanks for your offer.

John

At the higher frequencies, one way to make a 50 Ohm antenna is to arrange it
as a full wave loop, but make it about twice as high as wide. That is, you
end up with an antenna that is 1/3 wavelength high, and 1/6 wavelength wide.
It's a balanced antenna, so you don't need ground, but the whole thing has
to be well up in the air.

That's an interesting one I'll remember.

However, the idea is to make an unbalanced antenna with all the elements
connected to ground. The folded monopole is an excellent example.

Thanks.

John
