Default Linear Twin (2) Element Horizontal Wire Antenna - End-Fed Windom Antenna

FO&A,

This Week's 'new' Shortwave Listening (SWL) Antenna :

Linear Twin (2) Element Horizontal Wire Antenna - End-Fed Windom
Antenna
http://groups.yahoo.com/group/Shortw.../message/14164
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

-Note- These are the Larger 3/4" Round Barrel ones that
are usually provided with TV and FM Antennas and can be
bougth in Stores. They seem to work better as a Low Cost
Shortwave Antenna Matching Transformer; than the smaller
1/2" Round Barreled ones that are much cheaper.

RG6 Quad Coax Cable Feed-in-Line about 25 Feet Long

? WHY ? Two End-to-End "Linner" Horizontal Wires ?
MT:==================-------------------------------o
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 ~ 7.8 ~ 11.7 ~ 15.6 ~ 19.5 ~ 23.4 ~ 27.3

* 39 Feet ~ 1/4 WL for 49m Shortwave Band
~ 5.9 ~ 11.8 ~ 17.7 ~ 23.6 ~ 29.5

* 24 Feet ~ 1/4 WL for 31m Shortwave Band
~ 9,4 ~ 18.8 ~ 28.2

Currently Rigged "Flat" at about 17~18 Feet above ground level.

Might call it an End-Fed Windom Antenna . . . . .
