Dear Mr. Reg Edwards,

This is an interesting question indeed!

Well,
my wife yinSV7DMCdag has developed sometime an AVI movie

[ in ZIP form:

[ 850 KB

which deals among other properties of a filamentary dipole,
with its Radiation Resistance relative to the Input Terminals (Driving Point)

[ Please take a look if you like
[ in the part D of the movie,
[ at the bottom right of the screen

This is actually the Input Resistance Rinp
of a filamentary dipole of perfect conductivity in free space.

The ratio of dipole length L to wavelength lambda takes values up to 10,
but someone may maintain arguably that either
the limit of Rinp exists in general as infinity or does not exist at all.

Yours Sincerely,
