This is subject to much correction from people who are smarter than me, but my oversimplified description is that an orthogonal antenna basically consists of three loop antennas oriented in three planes that are at right angles to each other (X, Y and Z axes if you remember your basic geometry). The antenna are bidirectional in each of those planes.
With some associated electronic wizardry, you can compare the signals received by each antenna and establish the direction (in three-dimensional space) of a given transmitter. Sort of a method of electronic triangulation. I don't know how much application it has in ham radio. I don't recall seeing any ham call signs associated with the documents I read during my Google search! It looks like most of the uses are industrial. Hope that gets you started, and like I said, probably subject to some clarification by brainier people. 73, Ken Alexander VE3HLS --- On Fri, 11/12/10, Lee Buller <[email protected]> wrote: From: Lee Buller <[email protected]> Subject: [Elecraft] Education please To: "Elecraft Reflector" <[email protected]> Date: Friday, November 12, 2010, 9:32 AM What the heck is a orthogonal antenna? Would someone define it or give an example? I have Googled it but it is all mumbo-jumbo to me. Lee Buller K0WA Still learning after all these years! In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? Common Sense is the image of the Creator expressing revealed truth in my mind. - J.
