Making of a J Pole Antenna

Cutting the copper pipe with a pipe cutter.
Assembling the antenna for a perfect fit.
Sweating the fittings together with flux, solder, and a torch.
Attaching the coax to the antenna with clamps.

Testing to see if the antenna is a good match to the Ham Radio with a SWR meter (Standing Wave Ratio).

Fox Hunt

Group of the Hams from the KARC BMRC Ham Club that made antennas for Fox Hunting.
Showing a few of the steps in making the antenna. Here the coax is held in place on the plastic pipe with a wire tie and tape. The coax is split and bringing out the copper braided wire.
Soldering the coax to the cooper wire.
Attaching the soldered wires and measuring tape with clamps.
Tightening the clamp while keeping the tape straight.

Radio direction finding is used to find sources of interference to any form of wireless electronic communications, including broadcast and two-way radio, television, and telephones. It is also used to track missing or stolen cars and other property. Search and rescue workers use it to find persons in distress. Emergency Locator Transmitters in downed aircraft are tracked with RDF techniques. As a game Ham Operators call it Fox Hunting.
