Homebrew 10/20/40m EFHW vertical Antenna "SOTA". Post #1230.

If you can't view this video, please enter this title URL into your browser search box: This end-fed halfwave antenna from 2E0VOV is based on the popular "Par Endfedz" QRP multiband antenna.  In this case, 2E0VOV used a FT140-43 toroid with a total of 16 windings and a 100 pf capacitor across the feed point. The 40 meter loading coil is made from 58 feet/17.68 meters of enamel wire wound tightly on a 20 mm form. A good, simple, inexpensive antenna suitable for portable and emergency operations.

Simple Ham Radio Antennas--Homebrew 10/20/40m EFHW vertical Antenna "SOTA". Post #629.

If you're having trouble viewing this video, please insert this address into your browser search box:  In this video, 2E0VOV shows us how easy it is to design and build a vertical half wave antenna covering the 10, 20, and 40 meter amateur radio bands .  This antenna closely resembles the popular "Par End fedz" QRP multiband antenna.  The only thing I would add to this otherwise excellent presentation, is a quarter wave counterpoise wire for each band of use. These wires could be attached to the ground lug of the antenna transmatch ("tuner") or at the base of the antenna mast.  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 communit with a free email subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).
