Do-It-Yourself "Alternative" # 2 to the Watson-Miller
Shortwave {Listener} (SWL) Receiving {Only} Antenna
Still working on a Home Brewed Sort-of-Look-a-Like Antenna
using Copper Tubing and a PVC Pipe Mast Support; along
with a 9:1 Matching Transformer and Coax Cable feed-in-line.
It's a Work-in-Progress with two false starts {Whoops}
The 1/4" Copper Pipe ~ 15 Feet Long Antenna Element
comes from a Icemaker Water Supply Installation Kit

Ten Foot Piece of PVC Pipe Upper-Mast
[ Antenna Element Shape Support ]
Attempting to get a 6" Radius Top And Bottom
RF Junkie 9:1 SWL-1 Long-Wire Feeder [ Matching
Transformer ] with So-239 to "F" Adapter
RG-6 Quad-Shield Coax Cable feed-in-line 50~100 Feet.
21-Foot piece of Top-Rail for the Bottom Mast
[ Free-Standing with a Ground Anchor ]
The Fold-Up and repeated problem so far has been
'forming' the 1/4" Copper Tubing Antrenna Element
with the Straight Parallel Runs and the Six-Inch
Radius at the Top and Bottom.
A Plastic Chop-Stick is being used to Fill the 3" Gap
between the Two Ends of the the "C" and hold them
in 'fixed' Alignment with the other parallel run.
Still have not figured-out whether to use the Top-End
of the "C" Gap or the Bottom-End as the Feed-Point.
? Any Suggestions as to Which and Why ?
yes - i like play with antenna projects - iane ~ RHF {pomkia}
