Three-Wire Dipole Antenna. Post 1855.

If you can't see the video, please insert this title URL into your browser search box: I'm always looking for unusual antennas that can expand the basic capabilities of simple dipoles and verticals.  The Three-Wire Dipole is such an antenna. In this video, Stan Gibilisco (W1GV) shows us how to build this unusual antenna and describes its advantages and drawbacks.  The antenna is fed with open wire (300 ohm twin lead, 450 ohm ladder line, or homebrewed 600 ohm feed line) and uses an antenna transmatch (i.e. "tuner") with optional balun to reduce RFI and SWR. The space between the top horizontal antenna element and the bottom antenna element is approximately 12 inches /30.48 cm.  The antenna is capable of multiband operation.  If you're looking for a different kind of dipole, then the three-wire dipole may be what you're looking for.

Three-Wire Dipole Antenna. Post #1052.

If you can't view this video, please enter this title URL into your browser search box: 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. For the latest Amateur Radio news and inform
