MAIN LOOP RESPONSE.  A RIGOROUS ANALYSIS OF THIS TYPE OF HF LOOP WAS
CARRIED OUT BY K. SIWIAK, KE4PT, AND R. QUICK, W4RQ.  ED.  I USED STEVE
YATES, AA5TB, SMALL TRANSMITTING LOOP ANTENNA CALCULATOR TO ESTIMATE THE
PERFORMANCE OF THIS ANTENNA.  FOR EXAMPLE, ON 20 METERS, AND IF THE LOOP
SERIES LOSS RESISTANCE ADDS UP TO NO MORE THAN 30 M, THE CALCULATED
EFFICIENCY IS AS HIGH AS 4 DB.  AN EFFICIENCY OF 40 MIGHT SEEM TERRIBLE,
BUT IT IS LESS THAN 1 S UNIT.  IF YOUVE USED A SMALL HF MAGNETIC LOOP FOR A
