Simple Ham Radio Antennas--Open-Wire Dipole Antenna. Post #694.

If you're having trouble viewing this video, please insert this title link into your browser search box:  In this video, Stan Gibilisco (W1GV) shows us how to design, build, and use one of the simplist, most efficient, and easy-to-make HF antennas for radio amateurs.  With the use of open-wire, ladder line, or television twin lead and a balanced antenna transmatch ("tuner"), you can use any amateur radio band between 80 meters and 10 meters without cumbersome traps, add-ons, or difficult tuning procedures.  If you don't have a balanced tuner, you can run the ladder line into a 4:1 balun, and connect the junction to your antenna transmatch with a short length of 50 ohm coaxial cable.  To cover 80 through 10 meters, each segment of the open-wire dipole antenna should be approximately 20 meters/65.6 feet long.  This antenna is often called a "doublet".  Get this antenna as high as possible for the best DX coverage.  If you don't have two tall supports, then use this antenna as an inverted V, with a telescoping fiberglass mast as the antenna support.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).
