Double Extended Zepp Antenna  ^pop - This double extended Zepp provides 3 db gain over a dipole on the band it is designed for. Each side or leg is about 5/8 wavelength long.

The Moxon Rectangle on 2 Meters - We often think of the Moxon rectangle as strictly an HF antenna. However, its small size and special far field pattern lend themselves to some VHF applications. So let's see how to adapt the design to 2 meters (as a popular band choice) and also see a few of the uses to which we may effectively put the design.
