[Milsurplus] Ferrite Loop Antennas

[J Forster]

The loop I'm using is not resonant. I figured that would not be a good thing for
LORAN, since it's a pulsed signal. The last thing I wanted was a bunch of ringing.
As I remember, I designed the loop to look like roughly 50 ohms at 100 KHz...  the
LORAN pulse frequency.

Best,
-John
