Today's 'new' Shortwave Listening (SWL) Antenna :
Linner Twin (2) Element Horizontal Wire Antenna
63 Feet Long - - - a la John Doty
Laid-Out : South-East to North-West (Far End) from the
Back of he Roof of the House to the Backyard
TV 'type' 300 Ohm to 75 Ohm Matching Transformer
RG6 Coax Cable Feed-in-Line about 25 Feet Long

? Why ? Two End-to-End "Linner" Horizontal Wires ?
MT:===============-------------------------------------o
Balun : 24 Feet Twin Lead and 39 Feet Litz Wire
.
* The 24 Feet of 300 Ohm Twin Lead is connected
across the 300 Ohm Side of the Matching Transformer.
* The 39 Feet of Litz Wire [ 50-Strands of # 41 AWG ]
is connected to one side of the Twin Lead. - Note the
other side of the Twin Lead is not connected at the
Far-End it Floats in Parallel.
* The Total Length is 63 Feet for the Longer
* Note the Shorter Wire is 24 Feet and it's Far-End
is not 'connected; and this "other' Side of the Twin
Lead Floats in Parallel to the Longer Side.
.
Sort of : Acts like One Wire -and- Acts like Three Wires :
* 63 Feet ~ 1/4 WL for 75m Shortwave Band ~ 3.9 Mhz
* 39 Feet ~ 1/4 WL for 49m Shortwave Band ~ 5.9 Mhz
* 24 Feet ~ 1/4 WL for 31m Shortwave Band ~ 9.4 Mhz
Might call it an End-Fed-Windom Antenna . . . . .

Wow. You need all that to pick up a 100,000 Watt station from Utah in
the S.F. Bay Area?- Hide quoted text -

Yep David,

In the Flat Lands of Oakland California there are at least
250, 000,000 Watts That's-250-Mega-Watts of Noise
Generators very near by -wrt- Salt Lake City.
