Multiband Dipole Antenna. Post #1216.

Experimenting with antennas and limited spaces is fun and educational.  In this video, we see how a garden in the UK can be used to accommodate a homebrew dipole antenna.  According to "Daz", this 108-ft/32.92 meter antenna works on all bands from 80 to 10 meters "without any problems." Although coaxial cable is used as the feed line into an antenna "tuner", he concedes that ladder line would probably work better. He used an "air coil" made from 7 turns of coax at the base of the antenna. Despite the antenna's appearance and length to fit dimensions, it worked well. Don't be afraid of trying various antenna designs--that's part of the fun of Amateur Radio.

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'

Simple Ham Radio Antennas--Multiband Dipole Antenna. Post #550.

If you're having trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/wH0RNIr9cqE.  This video from "Daz-26-PS-001", is another way to build, erect, and use a multiband diple with a minimum of cost.  According to Daz, each leg of his dipole measures 108-feet/32.92 meters, making this antenna a 3/2 wave dipole on 40 meters.  Daz says he can tune from 10 to 80 meters without difficulty using an antenna "tuner."  Apparently, this dipole antenna variant gets him some excellent contacts.  Also, he could have used 450-ohm ladder line , a 4:1 balun, a short length of coax, and an antennas "tuner" to load this homebrewed dipole.  Ladder line would have allowed him a bit more efficiency and an easier way to "tune out" high SWR .  Nicely done video.  Music background:  "Kalimba" b Mr. Scruff ( Google Play , iTunes , and eMusic ).  For the latest Amateur Radio news and events, please check o
