This photo shows Ron KC9SNI (right), assisted by grandson Josh, raising Ron's implementation of the "AE5JU Field Day Antenna."  This multi-band antenna employs simple, inexpensive components and is relatively easy to construct. It covers 75, 40, 20, and 15 meters with a little assist from a tuner.  I made contacts without difficulty using this antenna during Field Day 2013.  I found the antenna design at :  www.hamuniverse.com/ae5jufielddayantenna.html
