Ah yes....so true.....I've learned a lot about loops since associating with
Mr. Ashlock and the rest of the lowfer
community. The only antenna in use here now is a 40 foot square loop for lf
receive and hf transmit. In addition, I
have the 10 ft dia. rotating loop. So, at this qth, it's
loopidy doo.
Regards,
Tom N8TL
