JD,
Something Different - - - On-the-Fence Loop Antenna for the Shortwave Listener (SWL) You should first install an 8-Ft Ground Rod at the Foot (Base) of the new Fence. Note - This will be the Starting and Ending Point for your Wire Antenna Element + The Mounting Place for your Matching Transformer { A Balun = Loop-to-Coax } + The Connecting Point for your Coax Cable. Start by running the Wire Antenna Element out along the Bottom of the Fence to your Far-Point. Then a short Wire Antenna Element Leg-Up to the Top of the Fence. Next run the Wire Antenna Element back along the Top of the Fence to your Starting-Point. Finally a a short Wire Antenna Element Down-Leg to the Bottom of the Fence. Mount your Matching Transformer to the Ground Rod Connect your Coax Cable to the Matching Transformer. Connect your Two Wire Antenna Element Ends to the Matching Transformer. You now have an On-the-Fence Loop Antenna [ Bent-Around-the-Fence ] FWIW - Two On-the-Fence Loop Antennas One Rigged on the Fence along one Side of the Yard One Rigged on the Fence along the Back of the Yard Set at 90 Degress and being about 8-ft apart at their Starting Points from a common Corner can give you more Receiving Antenna Options. Note - Separate Ground Rods, Baluns and Coax Cable Feed-in-Lines are recommended if you choose to use two On-the-Fence Loop Antennas. As to the Question of Antenna Wire Size : # 14 AWG Insulated Copper Wire with 19-Strands and using PVC Insulation is cost effective and durable. HomeDepot type - THWN or THHN in 500 Foot Spools TIP - One of the most important details of an On-the-Fence Antenna is the Stand-Offs used to keep the Wire "OFF" the Fence and in the Air. TV "Stand-Offs" with Plastic Insulator Head and 3.5" Wood Screw base hardware.
