	Perfect Portable Antenna The Perfect Portable Antenna (PPA-20) is a lightweight end-fed Zepp antenna for the 20 meter band.  It packs up very small - the matching network, which goes at the driven end of the antenna, is shown here.  The red binding post connects to 1/2 wavelength of wire (33 feet of very flexible 24 AWG wire, included).  The far end can be suspended from a tree, a portable mast, or whatever is handy.  As a full 1/2 wavelength antenna, it needs no radial system, only a 3-foot counterpoise (included) connected to the black binding post.  It will handle up to 5 Watts, and is very efficient.  Now available for 40, 30, 17, 12, 15 and 10 meters.  It's available at the Lazy Dog Store
