Simple Ham Radio Antennas--WDØAKX Shack Quick Ham Radio Antenna Tour On Site. Post #552.

If you're having trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/LQxSVxAWekI. The beautiful antenna installation from Larry, the "Radio Ham Guy" (WD0AKX) probably doesn't qualify as a "simple" antenna installation, but it does show what a little time, effort, and planning can do for a compact multi-band DX antenna.  Larry's antennas range from a triband beam to fan dipoles and from 2 meter beams to an 11-meter CB whip.  A very nicely designed antenna "farm" using a single 40-foot/12.19 meters Rohn 25-G tower.  For the latest amateur radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Simple Ham Radio Antennas--KG0ZZ's Amateur Radio Tower Stand. Post #551.


If you're having trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/0ZbfsuuoSDg. Thanks to Dave Turlock (KG0ZZ) for this interesting tower support project.  Dave used 5 sections of Rohn 25-G tower, with a top section of 8-feet/2.45 meters.  The total length of the tower is approximately 48-feet/14.63 meters. As with any tower project, you may want to get some help assembling and erecting the tower, preferably someone with tower experience.  Good luck!  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 e-mail subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

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 out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free e-mail subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--Antennas in the Attic: Ham Nation 215. Post #549.


If you're having trouble viewing this video, please insert the following URL into your browser search box: https://youtu.be/gFW-dre0OrQ.  Gordon West (WB6NOA) show how some hams are using antennas in unexpected places, including attics.  The antenna in this installation is a compromise that works.  While not perfect, this stealth or hidden antenna gets this radio amateur on the air in grand style without nosey neighbors complaining about the loss of their view.  The key here is low power, digital modes, and creative design.  For the latest Amateur Radio news and events, please check out the blog sidebar.

Simple Ham Radio Antennas--Topbeam Low Band RX Antenna model WF300 - Installation. Post #548.


If you can't see this video, please insert this URL into your browser search box: https://youtu.be/jMJxc7IXtiM.  Although this antenna project is not "simple" as I've used the term, it's still an interesting video of a major antenna installation--in this case the Topbeam Low Band RX Antenna model WF300.  The antenna was installed under questionable weather conditions at Sergio's (PP5JR) QTH in Florianopolis, Brazil.  The installation was done fairly quickly by a well-trained tower climber and his team.  The only practice I question is raising this antenna during "bad" weather.  You just can't take a chance with rain clouds around 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 e-mail subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Ham Radio Go Box gobox. Post #547.


If you have trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/HgNUbsj-5XU.  Every radio amatuer should have a "Go Box" for portable and emergency use. In this video from "danpass12" (AK4PX), we see a simple, straightforward arrangement using an old military ammunition box, an ICOM-703 Plus HF transceiver, a self-designed 3D printed control panel, a charger suitable for solar panels, and a 9AH battery.  This setup is easy to duplicate with an extra rig you may have handy in your shack and some materials from your neighborhood building supply store.  It pays to be prepared.  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 e-mail subscription or by tapping into the blog RSS feed.

Simple Ham Radio Antennas--Ham Radio DX On Very Short Antenna - A Must See NXØP. Post #545.


If you're have trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/KmeZ25jabWQ. Thanks to Larry (WD0AKX)(Ham Radio Guy) for this intriguing video showing Roger (NX0P) using a compromise antenna with good results from his QTH near Glenville and Albert Lea, Minnesota.  The antenna is a MFJ-1620HT (for 20 meters), using a metal plate and three approximately 16.5 feet/5.03 meters radials.  He was using about 100 watts into this shortened antenna and made quite a few contacts.  Although short antennas are, at best, compromises, they can perform reasonably well with a decent ground or counterpoise system.  Roger's antenna arrangement would be suitable for those living in deed-restricted properties or for those favoring portable or emergency operations.  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 e-mail subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).
