Three-Wire Dipole Antenna. Post #1052.

Here's an interesting dipole design for antenna experimenters.  The three-wire folded dipole or T3FD was popular during the 1950s and 1960s, with several companies, including B & W, marketing the antenna to the military, commercial interests, and radio amateurs.  The antenna has a broad bandwidth, high impedance, and exhibits high efficiency.

In this video, Stan Gibilisco (W1GV) explains the theory, design, and operation of this classic antenna.  In Stan's version, the 1/2 wavelength top section consists of three parallel elements, with the center element connected to a balanced feedline, which goes to a transmatch (i.e. "tuner") and then to your HF transceiver.

Although this antenna is a bit of a curiosity, you may want to build one just to see what it can do for your signal.
