Extended Double Zepp Antenna

Image
  How would you like to improve the gain of the "classic" dipole antenna? You can if you build an Extended Double Zepp Antenna, based on this design from Stan Gibilisco (W1GV). The EDZ antenna consists of two collinear 0.64 wavelength elements in phase, resulting in an approximate gain of 3dB over a dipole along the main lobe. Stan gives you all the information you need to build this fairly large antenna.

Practical Foil Metal Antennas

Image
  If you've run out of wire and metal tubing for your next antenna project, why not use widely available copper or aluminum metal tape for that next portable antenna? In this video, John Portune (W6NBC) explores the design possibilities of metal foil tape, which can be found at the nearest hardware or home improvement outlet. John shows us how to create "various small sized tape HF & VHF antennas" from that roll of foil tape you may have hidden in your garage. The projects are easy-to-make and offer acceptable performance for home station or portable use.  No special tools or metal fabricating expertise are required to make these antennas.
