Do you know the approximate input impedance of
a 0.1 lambda diameter single turn loop?
__________

About 2.5 ohms.

Can you guide me to a web site where that loop input impedance is given
in
R+jX? I will set up and measure some loop input impedance at 137 MHz
within the next few days. But, I'd like to have a better "feel" for what
I'm doing before I take time to build the loop and set up the test
equipment.

Thanks
Jerry


Hi Jerry,

The free version of EZNEC should cope with this simple problem. To
answer your question it reveals:
Impedance = 4.887 + J 853 ohms

Thanks Richard I like it when you do all the work and I just sit here
and read off the good data. If I wasnt so lazy I'd go out and build a loop
so I can se how it works,
I'd like to get a loop to match to 100 ohms of +jzero.

Thanks again
Jerry
