Since our subject is still baluns, I have used Fiberglass tape on Torroids
and solenoid windings because they heat up. Other things deteriorate. I
use that because I have some. I couldn't tell anyone what would be best in
the long run for UV. It is a big problem. Heat means loss. I prefer to do
away with the need for baluns and other elements that don't contribute to
radiating the energy.



Go to a larger core, stack large cores to lower power density per cubic
centimeter of core material--adjust core material to compensate for
increased inductance, etc.

Proper functioning of the balun hinges on proper design/material, of
course ...

Now is one is designing an electric heater, ni-chrome wire might be
implemented in the design--perhaps a "ceramic tape", etc. ... 8-)
