1. [Antennaware] Dual fed K9AY (score: 1): Author: "Hal Kennedy" <halken@comcast.net>; Date: Tue, 26 May 2009 12:05:14 -0400; Excellent thread here guys. So much so that I have switched out of digest mode and into real time mode. A few notes on the K9AY - some perhaps more relevant than others. 1. The far field pattern is A; /archives//html/Antennaware/2009-05/msg00008.html (9,591 bytes)
