Would you like to increase the gain and directivity of your 15 meter dipole antenna?  You can, if you make a few modifications to its length and are willing to use a balanced feed line and an antenna transmatch (i.e. "tuner").

This video is based on a design by George Murphy (VE3ERP).  The Extended Double Zepp Antenna is simple, efficient, and exhibits nearly 3 dBi gain over the "classic" 1/2 wavelength horizontal dipole.

I've used a variety of extended double zepp antennas during ARRL Field Days and can attest to their outstanding performance.  The major limiting factor of this antenna is the extra space needed for each antenna element--which will be 5/8 wavelength each compared to 1/4 wavelength each for the regular dipole.
