Extended Double Zepp Antenna, Post 1850.

If you're thinking about a new antenna for the ARRL Field Day (last full weekend of June), why not consider the "Extended Double Zepp" for your portable station? 

The EDZ is a collinear array of two 5/8 waves in phase that can deliver up to 3dB of gain for your favorite amateur radio band.  Because EDZ's can be a bit large (1.25 wavelengths measured horizontally), you may want to consider something like 20, 15,or 10 meters for this fairly simple project.

In this video, Stan Gibilisco (W1GV) explains the theory and operating parameters of this antenna which can deliver better performance than the basic dipole antenna.

According to AC5UP, the EDZ antenna "is easy to build, isn't fussy about height or proximity to other wires, can be tuned to a broadband 1:1 match, and makes a dandy general purpose SWL antenna that 'hears" extremely well."
