"Receive Only" Shortwave Listening (SWL) Antenna - Think 9:1 Matching Transformer
 
FinalQuest,

If this is for a "Receive Only" Shortwave Listening (SWL) Antenna
Then Think 9:1 Matching Transformer - Which is sometimes called
a Magnetic Longwire Balun (MLB).

LOW NOISE SHORTWAVE LISTENING ANTENNA :
The Random Wire {Longwire} Antenna
+ plus the 9:1 Matching Transformer
+ plus the Remotely Located Ground Rod
+ plus the Coax Cable feed-in-line
Equals = The design concepts {elements} of the
"Low Noise" Shortwave Listening (SWL) Antenna

ABOUT THE "LOW NOISE" ANTENNA 'DESIGN CONCEPTS':
A Random Wire Antenna Element coupled via a 9:1 Matching
Transformer at the Near-End of the Antenna with a Ground
Rod and Coax Cable Feed-in-Line to the Receiver. This is
the basic SWL Antenna that uses the "Low Noise Antenna"
'design concepts' that were popularized by John Doty.
