Lest there be any confusion: an antenna IS a transmission line.

In fact, there is a formula for calculating the Z0 of
a single horizontal transmission line wire above ground.
#14 wire at 30 feet is very close to 600 ohms. #14 wire
at 30 feet describes a lot of dipoles.

Are there any calculations or charts for centre impedance of a dipole in
free space, starting from zero length, and going out to infinity?
