Simple Ham Radio Antennas--Six Meter Folded Dipole Antenna. Post #792.

Image
If you're having difficulty in viewing this video, please insert this title link into your browser search box: https://youtu.be/qbje13U6hC4.  Here's a simple, easily made folded dipole antenna for the 6 Meter Amateur Radio band.  Claude Jollet does an excellent job of explaining the design and construction of this antenna. According to Claude, the folded dipole is made from ladder line, fed with ladder line, and matched with a 4:1 "step down coaxial balun" at the bottom of the transmission line.  The antenna is resonant at 50.4 MHz.  The reported SWR is 1.3 to 1 between 50.0 MHz and 51.0 MHz.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Simple Ham Radio Antennas--Open-Wire Dipole Antenna. Post #791.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/wMPk45MVFp.  Well-done, easily understandable tutorial on the theory, design, and use of an open-wire dipole antenna for the HF amateur radio bands.  This antenna is a simple, efficient, and proven HF antenna design that will give you many hours of pleasure as you search for contacts on the amateur radio bands.  Cut the antenna elements for the 80 meter band, feed the antenna with open-wire, and use a balanced tuner or tuner with balun combination, and you'll have an antenna that will cover all amateur radio bands from 80 meters through 10 meters.  If you can only build one HF antenna on your property, go for the open-wire dipole with open-wire feeders.For more information on this dipole antenna, contact Stan Gibilisco (W1GV) at http://www.sciencewriter.net.  For the latest Amateur Radio news and events, please check out the blog sidebars....

Simple Ham Radio Antennas--HF tape measure horizontal dipole antenna. Post #790.

If you're having difficulty viewing this video, please insert this title link into your browser search box: https://youtu.be/PiU6x9aZT7A.  KI4PMI and NC4FB present an interesting approach to building a horizontal dipole antenna covering Amateur Radio Bands from 6 meters to 40 meters.  The antenna elements are steel tape measures, which you can find at hardware stores and home improvement outlets. I've built a few tape measure yagi/beam antennas for 2 meters, but I've never gone as far as building a tape measure dipole suitable for HF. Bands are selected by varying the lengths of the tape measures.  The video is well done and easy to follow.  This could be my next project.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--Ham Radio 40/80 Meter Inverted V Dipole Antenna. Post #789

If you're having difficulty viewing this video, please insert this title link into your browser seach box: https://youtu.be/wgIbWafVnSc.  I've always enjoyed Dave Turlock's (KG0ZZ) videos for their clarity, ease of understanding, and production value.  This video on how to make a 40/80 meter Inverted V Dipole Antenna is no exception.  This two-band HF antenna is easy to design and build.  Loading coils make this antenna a full-size structure on 40 meters and a shortened antenna for 80 meters.  This antenna would be ideal for radio amateurs who live on small urban lots.  If you have the room, you may want to add 160 meters to this antenna for some interesting contacts on "The Gentlemen's Band."  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--How to hide 20 Meter Ham Radio Antenna on Balcony

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/Puo3YB2NEfA. This is post #787 of a continuing series on Simple Amateur Radio Antennas. Here's another idea of how to use a "stealth" antenna to get on the air.  In this case, RLG261 uses some MFJ parts and a floor flange to hide his 20 Meter Ham Radio Antenna from prying eyes.  For this project, RLG261 uses a MFJ-347 diple mount with two MFJ-2620T antennas. The antennas are mounted with a 1/2"/1.27 cm floor flange using a 1/2"/1.27 cm by 8"/20.32 cm pipe.  The flange is secured to the rafters with #12 sheet metal screws measuring 3/4"/1.905 cm long.  RLG261 recommends this antenna for receiving purposes only, since it may violate the National Electrical Code.  He did use the antenna for a few short QRP transmissions (less than 10 watts) and was satisfied that the antenna functioned well. You may find this antenna usable in ...
