Basic Antenna ? -and- Better Antenna ?

CONSIDER BUILDING A "LOW NOISE" ANTENNA:
..
Try building an Improved SWL Random Wire Antenna that uses a
9:1 Matching Transformer (Balun / MLB) then you may not see

This is the so called "Low Noise" SWL Antenna.

Three "Must" Links to Read -wrt- Low Noise 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
* Good 'earthen' Ground Rod and Wire

This is the basic SWL Antenna that uses the "Low Noise Antenna"
'design concepts' that were {popularized} by John Doty.
