For a mid-UHF fractal antenna, what kind of power can be used to
transmit, 100 watts, 1000 watts, 10,000 watts...?

I've had such antennas at very high QRO, but not for ham use.

Some designs, as with antennas in general, will arc at very high voltages.
Others will not.

It takes experience to pick the design that deals with the specs, including a
HV spec.

That's a commercial issue and beyond the scope of this NG.

Who sells them? "Commercial" indicates that such antennas are in production
and being offered for sale.

Look in the yellow pages under heating elements.

Yes. Drop me an e-mail and I'll be happy to provide details.

Why? You posted the "commercial" claim in a public forum, please reply to
same. I simply would like to know....if such antennas are commercially
available, then please provide a URL or sales site with the information on the
antennas. As an engineer, I am always interested in new/different technology,
thus the desire to look at a commercial unit application. Or are you getting
Shakespearian on me?

Since I don't know who you are, it would be helpful to be professional and take
it off line.

Fractal antennas ... turned out to be useless. That's how I understand it.
It is not a myth, as someone here said it. Drawing "fractal dipole" is shown
in "Antennas for all applications" - there is such a book. It,
anecdotically, does not do you much of anything.
Looks fancy, that's it.

There were bunch of articles promising miracles, but it did not work
according to the promises, otherwise we would hear about it, see them
around.

Fractal antennas are a myth.

I have yet to see one in QST or at the very least e-Bay®.
