 ```Terry and Guy, Thanks for the replies. I am using EZNEC+. The gain difference is as Terry commented; I hadn't set the Az angle to 45 degrees for the El plot. It makes sense now. 73 Andrew ----- Original Message ----- From: "Terry Conboy" To: "Andy Ikin" Cc: Sent: Thursday, July 09, 2009 3:43 AM Subject: Re: [Antennaware] 4 sq.
