If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=G2x67h7-cwI. In this post, Gil ("Radio Prepper") finishes his 49:1 Half-Wave End-Fed Antenna Transformer begun in our previous article (Post 2014, 07 October 2019). Now he field tests the device on a variety of amateur radio bands, including 6 meters and 30 meters.  The transformer performed well from 80 meters through 10 meters. Gil does an excellent job in combining theory and practice to produce a video that is clear, concise, and well-paced.

40M Delta loop antenna (horizontal) set up, Part 2.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=zFbJ7xym_Dg. In part 2 of this video tutorial, "DENMONKEY" completes the initial design, construction, and configuration of his 40 meter delta loop antenna.  He then raises the antenna and makes a few minor adjustments before the testing cycle begins.  The delta loop antenna is a good choice for radio amateurs who can only erect one HF antenna on their property.  For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.infor. http://www.arrl.org. http://www.arrl.org/arrl-audio-news (a weekly podcast which is updated each Friday afternoon). https://hamradiohawaii.wordpress.com https://bigislandarrlnews.com. https://amateurradionewsinformation.com (Amateur Radio News & Information). https://www.eham.net. http://www.southgatearc.org.

Simple Ham Radio Antennas--80-6 meter OCF Dipole Antenna for SHTF or Backpacking Part 2

If you're unable to view this video, please insert this title link into your browser search box: https://youtu.be/H7w-dji-Nv4.  This is part 2, of how to build and use an OCF 80-6 meter Dipole Antenna suitable for portable, emergency, or even for HOA/CC&R-restricted areas. This is post number 757. In this video, "survivalist2008" pays particular attention to the importance of an antenna transmatch to make sure your rig isn't damaged by the high SWRs found on this antenna system.  "Survivalist2008" (John) (KU4JZ) also describes the battery system he uses to operate in the field. John's Off-Center-Fed-Dipole is simple, inexpensive, and highly portable.  After he finishes for the day, John simply winds up the antenna wire on a trout fishing reel.  A nice antenna for portable use.  For the latest Amateur Radio news and events, please check out the blog's sidebars.  These news feeds are updated daily.

In this video, Randy completes his radio room and erects a Par End-Fed Quad Band antenna to finish the process. He used a MFJ -269 antenna analyzer to check out the performance of his new antenna.  A very nice video that can give you some ideas about rearranging your own ham shack.  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 .

Simple Ham Radio Antennas--Vertical Antenna 5/8 wave for 15 mtr ham radio band, Part 2. Post #584.

If you're having trouble viewing this video, please insert this URL into your browser search box:  https://youtu.be/ArigfAFVu84.  This is part 2 of Tommy Horozakis's tutorial on how to design, build, erect, and use a vertical 5/8 wave antenna for the 15 meter ham radio band.  His initial design and test produced some strong signals at his QTH.  The project is simple and involves only a few parts from your "junkbox" or from the nearest hardware store or home improvement outlet.  This would make a great weekend project.  If you build this antenna carefully, you could get a theoretical 3 dB signal gain over a 1/4 vertical antenna.  Don't forget to install a radial ground or counterpoise system.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.
