Or it may be simpler to add just one wire at a time and connect it. If you don't get the results you expected, either edit the information entered for each wire or delete the wire and try again. Thanks to Jerry KM3K for these and other suggestions. This is also known as the "right-hand rule". Engineering and amateur radiation patterns use an elevation angle instead in which 0 degrees represents the XY plane the horizon and increases toward 90 degrees at the zenith straight up. The inevitable confusion is regrettable but the two conventions are well-established. It covers a lot of background and has many links to other tutorials and references. Excellent for the reader interested in knowing what other techniques and tools are available. This course might be appropriate once the material in Antenna Modeling for Beginners is understood.However, Version 3 has one big advantage compared to later versions. It costs you nothing! Furthermore, even though it is outdated, its capabilities are adequate to model most antennas commonly used by amateurs. The radiation field produced by a transmitting antenna system having any known arbitrary current distribution can be found by adding the separate fields produced by elementary lengths of thin conductors with each elementary length treated as a very small radiating doublet antenna.
