Simple Ham Radio Antennas--Simple Loop Antenna for 20-10 meters. Post #574.


If you have trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/y3_LIQ6G6e4. An excellent video from Lynn (NG9D), showing just how easy it is to build and erect a full wave loop antenna covering the amateur radio bands between 20 and 10 meters. You can change the polarization by attaching the feed line at various points around the full wave loop.  You will need an antenna transmatch (i.e. antenna tuner) to tune out the reactance as you switch bands.  I prefer using 450 ohm ladder line or 300 ohm television twin lead for my feed lines. These feed lines are attached to a 4:1 balun and then connected to my trusty Drake MN-4 antenna transmatch with a short length of RG-8X coaxial cable.  The loop is a quiet receive antenna and should give you about 2dB gain over a dipole antenna.  Loops are fun to make and can be assembled from materials around your shack or from the bins at the nearest hardware or building supply store. Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Simple Ham Radio Antennas--F8FKI, biggest vertical antenna for 160 Meter band in France. Post #571.


If you're having trouble viewing this video, please insert the following URL into your browser search box: https://youtu.be/XBFursd_wbc.  If you have the time, an experienced tower crew, and some money, you can erect the 160 meter antenna of your dreams like Manu Antoni (F8FKI) did in France. Of course, a few acres of land won't hurt either.  Manu's antenna installation rivals that of many AM medium wave broadcast towers in the United States, namely, he has a full 1/4 stick (177-ft/53.96 meters), a complete 120-radial ground system using 40 meters/131.2 feet of wire for each radial, and a sturdy loading coil.  With a little top loading, Manu could also work 630 meters (472 kHz-479 kHz), depending on licensing requirements.

Simple Ham Radio Antennas--40 Meter Inverted V Antenna - Build, Tune & Test! Post #570.


If you're having trouble viewing this video, please insert this URL into you browser search box: https://youtu.be/7za6gPWcNng. Another great antenna tutorial from Dave Tadlock (KG0ZZ).  In this video, Dave shows you how to design, build, and erect a 40 meter inverted v dipole antenna.  Most of the materials for this antenna can be found at the nearest hardware or home improvement store.  The inverted v gives a good account of itself and only uses one support to get the antenna above ground.  For multi-band use (40 through 10 meters), replace the coax feed line with 450 ohm ladder line or 300 ohm television twin lead.  Take this feed line and attach it to a 4:1 balun. Run a short length of 50 ohm coaxial cable from the balun to your antenna transmatch (i.e. tuner).  If you prefer using coaxial cable, the 40 meter inverted v dipole antenna can be used on its third harmonic to give coverage of the 15 meter ham band.  The SWR may be a bit high on 15 meters, so an antenna transmatch will come in handy. This is an excellent weekend project that won't cost a lot of money.  Building your own antennas is half the fun of amateur radio.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated regularly.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.

Introduction to the 6 meter amateur radio band 50 to 54 MHz. Post #565.


If you have trouble viewing this video, please insert the following URL into your browser search box: https://youtu.be/DqIOmDHceLs. Here is a good, basic tutorial on the "Magic Band" known as 6 meters.  The band can be considered "magic" because it displays characteristics of both VHF and HF propagation. The six meter band sits on the edge of worldwide propagation and line of sight operations. You never know what 6 meters will do on a given day.  The video is well-presented and easy to understand.  Antennas for this band are fairly short. A dipole antenna for 6 meters (at mid band) would measure approximately 9 feet/2.74 meters.  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.
