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
