Simple Ham Radio Antennas--Coat Hanger 2 Meter Yagi Antenna. Post #498.

If you have trouble viewing this video, please insert the following URL into your browser search box: https://youtu.be/fLOvSLXDudU. Another great antenna project from Dave Tadlock (KG0ZZ). This time, Dave uses common materials from around the house and workshop to design, build, and use a simple 2 Meter Yagi Antenna made from metal coat hangers .  Since metal hangers are getting rare these days, you can use brass rods, copper wire , or even the old aluminum elements from an outdoor television antenna .  I've built a few of these crude yagis in years past and have found them very useful on portable operations or in locations where I'm a good distance from a 2 meter repeater.  This would make an excellent weekend project.  Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

If you have trouble viewing this video, please insert the follow URL into your browser search box: https://youtu.be/IAiilzV8NpI. Excellent video tutorial from Dave Turlock (KG0ZZ) on how to build a simple, effective 2 meter backpack quad antenna for portable or home use.  You can use fiberglass rod, arrow shafts, or bamboo for the spreaders,  Some PVC pipe can be used for the boom.  The longest spreader on Dave's quad is 30-inches/76.2 cm and the boom measures 30 7/8-inches/78.40 cm.  Dave uses #18 AWG wire for the antenna and has trimmed the antenna so it's resonant at 146.20 MHz.  This would make an excellent weekend project.  The antenna will be directional.  Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated regularly.

Simple Ham Radio Antennas--Wifi antenna booster dish. Post 496.

If you have trouble viewing this video, please enter this URL into your browser search box: https://youtu.be/VZKc3PBs67c. Great homebrew, do-it-yourself "Wifi antenna booster dish" for your home station.  This project from Matthias Wandel is simple, effective, and cheap.  Although Matthias uses a pan lined with aluminum foil, you could use a stainless steel pot of similar dimensions for the reflector and get some improved range.  This simple reflector would work well in an apartment complex where you are some distance from a router.  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 (KIH6JRM).

Introduction to the 15 meters amateur radio band. Post #495.

Image
Well-done video tutorial on the 15 meters amateur radio band from "OfficialSWLchannel." This popular ham band covers the frequency range of 21.000 MHz to 21.450 MHz.  The band is available to all classes of amateur radio operators.  Novice and Technician operators are restricted to the CW portions of the band.  This band is an excellent daytime DX band and sometimes stays "open" through the sunset hour.  Antennas are fairly modest and easily assembled.  A quarter wave vertical for 15 meters is approximately 11-feet/3.35 meters long.  A 40 meter vertical can often be used on its third harmonic to operate on 15 meters with some loss of signal due to a slightly higher angle of radiation.  For the latest Amateur Radio news and events, please check the block 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
