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

What started out as a "snow day" project for Barbara Justice and her children ended up as a 40 meter/20 meter fan dipole configured as an inverted V antenna.  Barbara says a few modifications also allowed her to use the antenna on 40-20-15-10 and 6 meters.  Despite the antennas low height above ground, the overall results of this winter activity produced a useful, multiband HF antenna at a modest cost. The video takes you-step-by-step through the building, configuration, and use of this versatile antenna.  The assembly process is organized, efficient, and simple.  Just follow the instructions and you'll have an efficient multiband HF antenna in just a few hours.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=7za6gPWcNng.  The basic inverted V antenna is an incredibly easy to make and use antenna that will give your hours of radio pleasure.  In this video, Dave Tadlock (KG0ZZ) provides a detailed explanation and demonstration of how to design, build, erect, and use a 40 meter inverted v antenna.  His explanation is clear, concise, and detailed. Follow Dave's instructions, and you'll have little difficulty in building this versatile HF antenna.  Multiband use can be obtained if you feed the antenna with 300 ohm television twin lead, 450 ohm ladder line, or homemade balanced line.  To use these feed lines, you'll need a balanced antenna transmatch (i.e. "tuner") or a 4:1 current balun attached to your regular "tuner."  You can use any good quality 50 ohm coaxial cable to feed the 40 meter version of this antenna.
