40 Meter Inverted V Antenna–Build, Tune & Test.

Following the passing of Tropical Storm Iselle, many amateur radio operators in the Puna District of Hawaii Island are rebuilding their antenna installations.  High winds snapped many trees that supported inverted vees, dipoles, and even towers.  There’s nothing like starting over.  I have several antenna plans moving forward, including a 40/15 meter inverted v dedicated to the Hawaii Inter Island Net (7.088 Mhz, 0200 UTC, daily).  Unlike many of my former dipoles, I’ll feed this antenna with RG-8X coaxial cable, rather than 450-ohm ladder line.  This in- depth video  from Dave Tadlock covers just about everything you need to know about building an inverted v antenna.  Dave includes helpful construction tips, the necessary formulas, the type of wire to use, mast alternatives, and the use of an antenna transmatch (i.e. tuner).  The video is quite good, and it has given me a few new ideas.  Aloha de Russ (KH6JRM).
