Al,
A folded dipole is around 300 ohms. This explains the use of 300 ohm twin
lead
on many TV antenna on old. If you really want to delve deeply into the topic
the
link below will give you more than needed with some programs that will crunch
the numbers.

Enjoy,

Is there a nominal impedance or approximate impedance for a loop
antenna? For example, a dipole is considered 72-ohm, a bevarage 450-
ohm. What is a nominal loops Z?
I have a 4-1/2 foot diameter loop antenna with 12 turns paralled by a
capacitor for the antenna and one additional turn for the pickup coil.
The loop is for the 200 - 500kHz band. About how much is the impedance
of such an antenna? Thanks.
