Yodar,
The simplest and easiest T2FD Antenna is not Tilted -because- it is mounted on . . . . . . . . . . . . . . . . . . You Got It ![]() So it is a Terminated Folded on a Fence Dipole (TF2D) Antenna http://groups.yahoo.com/group/Shortw.../message/14517 Top-Wire runs along the Fence about a Foot below the Top. Bottom-Wire runs along the Fence about a Foot above the Bottom. Distance between the Top and Bottom Wires is 2~5 Feet Length of the Top and Bottom Wires is as long as your Fence. Feed-Point is at the Center of the Bottom Wire. - - - Place a Ground Rod here to to attach to the Coax Cable and the Feed-in-Line Side of the 4:1 Matching Transformer {Balun} Terminating Resistor 400 Ohms ~ 900 Ohms is located at the Center of the Top Wire. Start with 600 Ohms and work up or down to find out what works for you. The Top and Bottom Wire Ends are Joined at the Ends. Feed the 4:1 Matching Transformer {Balun} with a Coax Cable. WINDOM-IZE-IT Since this is not "Tilted" and is close to the Ground. The Frequency Variable Factor that Tilting provided for the Antenna can be achieved by placeing the Feed-Point and Terminating Resistor at the 38:62 Off-Center-Point of the Top and Bottom Wires. { Windom-Ize-It } Call this a Terminated Folded Windom (TFD) Antenna BUT . . . MY YARD & FENCE ARE . . . Fence Not Long Enough ? -or- Location Not Right ? Can't Mount this Antenna along one side of the Yard ? Mount it in a Corner along two adjacent Fence Sides and make the Feed-Point at the Corner. i b tilted and on de fence - iane ~ RHF . . .. . = = = On Aug 26, 4:30 pm, RHF wrote: - - - In , "Jeffery L.
