Small-Short Six (6) Wire Rotor Cable Flat Wire Multi-Element Antenna for Shortwave Radio Listening (SWL)
RHF
A Small-Short Six (6) Wire Rotor Cable Flat Wire Multi-Element
Antenna for Shortwave Radio Listening (SWL) can be built with
Philips Accessories M61422 75Ft. 3-Wire Flat {Conductor}
Rotor {Rotator} Cable
http://indoors.pricegrabber.com/electrical/m/33448312/
* Shortwave Band Coverage : 60m, 49m, 41m, 31m, 25m, 22m
in less than 50 Feet.
* Uses a 9:1 Matching Transformer (MLB) and Coax Cable
feed-in-line.
* Measure-Out and Cut the 75 Feet at 48.5 Feet creating
Two 3-Wire Pieces 48.5 Feet and 26.5 Feet.
* At one end of each of these 3-Wire Pieces carefully
separate the 3 Insulated Wires for about 3-Inches.
* Strip about an Inch of Insulation from each of the Wires
and Solder {Tin} them.
* Route all 6 of the Individual Wires through one of the Holes
of a Plastic Compression Antenna Insulator.
http://www.myinsulators.com/sluggo/images/nonglass/group-plastic-compression.jpg
About 6-Inches Wires should be sticking out Through-the-Hole.
* Fold-back these Through-Wires on to the main body of the
Wire Pieces and Secure with 3~5 Plastic Wire Ties around
all 12 of the Wires; the 6-Through Wires and the 6-Main Wires.
* Measuring from the Hole of the Antenna Insulator to the
End of the Longer 48.5 Foot 3-Wire Piece; it sould measure
48 Feet. Next from the same Hole measure out 39 Feet
and carefully Remove 1-Inch of Wire from one of the outside
Wires of the 3-Wires. Then from the same Hole measure out
32 Feet and carefully Remove 1-Inch of Wire from the 'other'
of the outside Wires of the 3-Wires.
* Measuring from the Hole of the Antenna Insulator to the
End of the Shorter 26.5 Foot 3-Wire Piece; it sould measure
26 Feet. Next from the same Hole measure out 20 Feet
and carefully Remove 1-Inch of Wire from one of the outside
Wires of the 3-Wires. Then from the same Hole measure out
17 Feet and carefully Remove 1-Inch of Wire from the 'other'
of the outside Wires of the 3-Wires.
* Secure the Two 3-Wire Pieces together every 4~5 Feet with
Plastic Wire Ties.
* Use a second Plastic Compression Antenna Insulator
at the Far-End of the 48.5 Feet Piece of 3-Wire Rotor Cable.
* Rig Nylon/Poly Ropes through the 'other' Holes of the
Insulators.
* Solder all 6 of the Individual Wires of the two Pieces
of Rotor Cable together.
* Connect a 9:1 Matching Transformer (MLB) to these
joined 6-Wires.
* Connect a Coax Cable to the Coax Connector of the
9:1 Matching Transformer (MLB).
* Rig your Six (6) Wire Rotor Cable Flat Wire Multi-Element
Antenna as a :
* * Horizontal Wire Antenna using the Radio Shack's Ground
via the Coax Cable.
* * Bottom-Fed Sloper set at 45 Degree with the Feed-Point
Matching Transformer Grounded at the base of the Antenna.

for Shortwave Radio Listening (SWL)
FWIW - This Shortwave Radio Listening (SWL) Antenna can be
constructed using the same Two 3-Wire Pieces of Flat Rotor
Cable the Longer piece 48.5 Feet and the Shorter piece 26.5
Feet as the Opposing Arms of a Windom Antenna.
Small-Short Six (6) Wire Rotor Cable Flat Wire Multi-Element
Antenna for Shortwave Radio Listening (SWL)
http://groups.google.com/group/rec.radio.shortwave/msg/27368f23abd93445
Note - the Ground Foot Print of the Shortwave Radio Listening
(SWL) Antenna increases from 50 Feet to 75 Feet along the
surface of the Ground.
Plus a Dipole type 4:1 Matching Transformer {Balun} is used
between the Opposing Arms of a Windom Antenna; instead
of the Longwire type 9:1 Matching Transformer {UnUn - MLB}.
Route the Longer 3 of the Individual Wires through one of the
Holes of a Plastic Compression Antenna Insulator.
http://www.myinsulators.com/sluggo/images/nonglass/group-plastic-comp...
About 6-Inches Wires should be sticking out Through-the-Hole.
Fold-back these Through-Wires on to the Main Body of the
Longer Wire Piece and Secure with 3~5 Plastic Wire Ties
around all 6 of the Wires; the 3-Through Wires and the 3-Main
Wires for the Longer piece.
Use a second Plastic Compression Antenna Insulator
at the Far-End of the Longer 48.5 Feet Piece of 3-Wire
Rotor Cable and Secure with 3~5 Plastic Wire Ties.
Route the Shorter 3 of the Individual Wires through the 'other'
Hole of a Plastic Compression Antenna Insulator.
http://www.myinsulators.com/sluggo/images/nonglass/group-plastic-comp...
About 6-Inches Wires should be sticking out Through-the-Hole.
Fold-back these Through-Wires on to the Main Body of the
Shorter Wire Piece and Secure with 3~5 Plastic Wire Ties
around all 6 of the Wires; the 3-Through Wires and the 3-Main
Wires for the Shorter piece.
Use a third Plastic Compression Antenna Insulator
at the Far-End of the Shorter 26.5 Feet Piece of 3-Wire
Rotor Cable and Secure with 3~5 Plastic Wire Ties.
Rig Nylon/Poly Ropes through the Un-used Holes of the
End Insulators; and both Holes of the Center Insulator.
Solder all of the Individual Wires of the two Pieces of Rotor
Cable together 3- Long together and 3-Short together
Connect a 4:1 Matching Transformer (MLB) to these
two sets of 'joined' Wires : 3- Short ones to one Matching
Transformer Connection and 3- Short ones to the 'other'
Matching Transformer Connections.
Connect the Coax Cable to the SO-239 Jack of the 4:1
Matching Transformer.
The Coax Cable is run/routed up to {near} the elevated Off-
Center Support of the Windom Antenna {Off-Center Dipole}.
Your still have the basic Six (6) Wire Multi-Element Antenna
for Shortwave Radio Listening (SWL) -but- with a slightly
bigger Signal Capture Area.
The 4:1 Matching Transformer is elevated in the Air near the
Apex of the Windom Antenna {Off-Center Dipole}.
The Ends of the Arms of the Windom Antenna {Off-Center
Dipole} can be Rigged 'Flat" -or- 'may-be' lower that the
Center. 30 Degrees Off the Horizontal or 120 Degrees
between the Arms is good.

Rig your Six (6) Wire Rotor Cable Windom Antenna
{Off-Center Dipole} Antenna as a :
* Horizontal Flat Windom Antenna using the Radio
Shack's Ground via the Coax Cable.
* Off-Center-Fed Inverted "V" Antenna set at 120 Degrees
using the Radio Shack's Ground via the Coax Cable.
