For One and All,
Twin (Paired) Flat-Wires as Noise Cancelling Wire Antenna Elements
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/6712
IMHO - Twin (Paired) Flat-Wires [TPFW] (the Un-Twisted kind) can be
put to good use as "Receive Only" Shortwave Listener (SWL) Antennas.
Two very common TPFW Wires to used as Wire Antenna Elements :
Common Speaker Wire and Common 300 Ohm Twin Lead can be
employed as a Low-Noise Antenna Element in several ways :
1. Replace the UnUn and Single Wire of a Random Wire, Inverted
"L" Antenna, Sloper with either of these TPFW Wires. Use a Balun
and Coax Cable and wire one of the two TPFW Wires to one side
of the Balun's Balanced Input and the other Wire to the other side
of the Balun's Balanced Input. At the Far-End of the Two Common
Wires; strip and twist the Wires together and Seal the Connection.
2. With a Dipole or other Balanced Antenna replace the Single Wire
with either of these TPFW Wires. Wire them to the Balun like a
Folded Dipole that is Tapped in the Center of One of the TPFW Wires
with both the End-Wires on each side; strip and twist together and
Seal the Connection.
3. A Vertical Wire Antenna for limited-space (no-space) when
nothing else can be done. Use a Balun and Coax Cable and wire
one of the two TPFW Wires to one side of the Balun's Balanced
Input and the other TPFW Wire to the other side of the Balun's
Balanced Input. At the Top-Far-End of the TPFW Wires; strip
and twist the Wires together and Seal the Connection.
All of the Above can be maked using TV 'type' Parts :
* 300 Ohm Twin Lead {or Speaker Wire} as the Twin Parallel
(Noise Cancelling) Flat Wire Antenna Element.
* TV 300 Ohm Matching Transformer (Balun)
* RG6 or RG59 Coax Cable with "F" Connectors.
NOTE - None of these are great Shortwave Listening (SWL) Antennas :
But they are made of easy to find common TV 'type' parts to build
them and putting them together is simple and understandable for
most Shortwave Listeners (SWL). An Easy-to-Do First Antenna
