[AB2E Darrell]

Greetings Hasan,
Check out OK1RR's excellent site, http://ok1rr.com/e107_plugins/content/content.php?content.38
specifically for an antenna called the Battle Creedk Special. It is a well-known antenna used by many dxpeditions, made for 40-80-160, using traps. The link above is for the wire version.
