Simple Ham Radio Antennas--Triband end fed half wave antenna for portable use. Post #587.

If you're having trouble viewing this video, please insert this URL into your browser search box: Here's another simple, effective, and easy to build antenna from Peter (VK3YE).  This time, Peter designs and builds a triband end fed half wave antenna that covers 40 meters, 20 meters and 10 meters.  The antenna is a half wave on 20 meters and a loaded half wave on 40 meters.  The antenna can also work fairly well on 10 meters.  A broadband transformer replaces the antenna coupler. Although this arrangement is less efficient than an L-match, it does allow instant band switching.  The bandwidth is very narrow on 40 meters (150 kHz).  This antenna would make an excellent antenna for backpacking, pedestrian mobile, SOTA, or emergency use. Peter got good results with his Yaesu FT-817 QRP rig.  This would make an excellent weekend project.  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 community with a free email subscription or by tapping into the blog RSS feed.
