For One and All,
Check-Out this simple Antenna Design. No CounterPoise - Portable Antenna System for QRP and QRO http://groups.yahoo.com/group/Shortw...a/message/6596 Note - This is a "CLOSED/COMPLETED" eBay Auction http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5828919956 IMAGE = http://www.bellimelgroup.com/images/Antenn1.jpg eHam "Reviews" for No CounterPoise Protable Antenna System NCPAS = http://www.eham.net/reviews/detail/4762 TECHNICALS : This No CounterPoise - Portable Antenna Antenna Aystem is 50 feet long and consists of a 25 foot long matching section and an intregral 25 foot long radiator. The matching section connects to your tuner or rig with internal tuner using high quality, color-coded, gold-plated connectors. The Manual provides complete details on how to use this Antenna. NOTE - At 50 Feet this End-Fed Half-Wave Dipole Antenna should be roughly Resonant at 9.35 MHz @ 31 Meter Band. The Wire Antenna Element 'appears' to be Landscaping Cable (Heavy Duty Zip Cord) that has Half of One Insulated Wire Removed and the other Parallel Wire Full Length. Basically like an End-Fed Dipole or "Zepp" Antenna. FWIW - This type of "Zepp" Antenna is as old as Radio and is best known as the "Zepp" Antenna named after the Zeppelin Airships it was commonly used on. http://webpages.charter.net/aa5tb/efha.html What is a Zepp {Zeppelin} Antenna ? http://www.eham.net/forums/Elmers/80122 The Zepp Antenna first saw daylight on the Graf Zeppelin on it's round the world flight back in the late 1920's. PAR Electronics End-Fedz Antenna http://www.parelectronics.com/end_fedz.htm http://www.universal-radio.com/catal...wire/4456.html PAR Electronics EF-SWL Antenna http://www.grove-ent.com/ANT8.html http://www.parelectronics.com/swl_end.htm http://www.universal-radio.com/catalog/sw_ant/2205.html NOTE - These Antennas are a full length half wave dipoles, but with an important difference. The coax connector is at one end of the dipole, where it is most needed. These Antennas can be mounted Horizontally, Vertically, Sloper or as an Inverted "L Antenna (My Choice). No Ground Plane or Counterpoise is needed. Portable operation could not be easier. Simply hang the far end from a tree limb -- the coax is at the bottom. Hang it up in a hotel window or string it up in the attic. End insulators are supplied making suspension easy. eHam "Reviews" for PAR Electronics EF-SWL Antenna http://www.eham.net/reviews/detail/3707 PAR = http://www.parelectronics.com PAR End-Fed Shortwave Listener's (EF-SWL) Antenna - by Larry Van Horn [N5FPW] http://tinyurl.com/cuthy Source - Monitoring Times - What's New" Reviews MT® 2003 READ - A Tiger by the Tail - or a 135 Foot End-Fed Multi-Band Dipole Data Compendium - by L.
