Simple Ham Radio Antennas--Multiband Dipole Antenna. Post #702.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/wH0RNIr9cqE.  Here's another simple, cheap, and easily constructed dipole antenna for your backyard, courtesy of "Daz" 026-PS-001) of the UK.  Working with readily available materials, Daz made a dipole antenna from a wire 108-feet/32.92 meters long, suspended it from supports in his backyard, and fed the antenna with 50-ohm coaxial cable terminating in an air-wound coil (7 turns of coaxial cable).  The coil was then connected to his antenna transmatch (i.e. "tuner").  Daz says the antenna works well on all Amateur Radio bands from 80 through 10 meters.  The only change I would make in this arrangement would be to fed the antenna with 300 ohm television twin lead, 450 ohm ladder line, or some homebrewed balanced line. Attach the feed to a balanced tuner (or to a 4:1 balun and then connect the balun to your tuner), and you'll have an easier time tuning the antenna from 80 to 10 meters.  Part of the fun of amateur radio is designing, building, and using your own antennas.  Daz's idea works, and it may work for you!  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!
