40 Meter Inverted V Antenna - Build, Tune

If you can't see the video, please insert this title URL into your browser search box: This is post 2084 in a continuing series on simple ham radio antennas.

Thanks to Dave Tadlock (KG0ZZ) for this excellent tutorial on designing, building, tuning and testing a basic Inverted V Antenna.

Inverted V antennas are excellent performers if you have limited space for a full half- wave horizontal dipole antenna.  In Dave's example, the end of each antenna segment is 11 feet/3.35 meters above ground, allowing sufficient space for people and animals to pass through without injury.

A few years ago, I built a variation of this antenna fed with 450 ohm ladder line.  That antenna covered 40 through 10 meters with the help of an antenna transmatch (i.e. "tuner").  Without a tuner, the antenna will cover part of the 15 meter band, using the third harmonic of 7 MHz.

The video is well-organized and easy to follow, especially if you lay out the materials in the way Dave has shown.  Just take your time. The end result is a versatile, efficient antenna that will serve you well for years.
