If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=MPk45MVFpY. This is post #975 in a continuing series on simple ham radio antennas . Here's another great idea for an inexpensive, efficient, and easily made antenna suitable for either home or portable use. In this video, science writer Stan Gibilisco (W1GV) shows us how to design, build, and use an open-wire dipole antenna .  This antenna, designed for the lowest HF band of your choice, and fed with 450 ohm ladder line , 300 ohm television twin lead, or 600 ohm balanced feeders and attached to your transceiver via a balanced ATU or a balun/"tuner" combination will cover several HF amateur radio bands with only one antenna. This particular antenna uses 450 ohm ladder line to feed two equal horizontal antenna elements, each measuring 20 meters/65.6 feet.  Used with a suitable ATU, this antenna will cover all amateur radio ban
