Sounds like you're describing Bruce Conti's superloop, Charles. http://members.aol.com/amhits/termloop.htm His contact information is on his website, http://members.aol.com/baconti/bamlog.htm, if you don't know him already. >I converted my 22-metre longwire into a EWE with 4.6-metre >"legs."

Koontz' original article found that signal strength on 160m increased with horizontal length, but that front to back ratio deteriorated after a ratio of horizontal to vertical of 4 to 1, at least in modeling. If you don't think you're getting enough signal, beef up those verticals for sure... Nick **************************************************************************** Nick Hall-Patch Victoria, B.C.
