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.
