Using Gain-Probability to Compare Antenna Performances
What is “Gain-Probability”? The attachments include the original QEX article and the GP Spreadsheet.
In its simplest form, Gain-Probability described in K9SO's QEX article combines the EZNEC calculated far field patterns of an antenna with published propagation data that predicts the incoming angles of signals from around the world. Combining these pieces of information gives great insight into antenna performance and is a probabilistic approach to comparing antenna performances (incoming signal angles are given as probabilities). Link to G-P program examples.
This article was published in the ARRL publication QEX Magazine in the Sept/Oct 2007 issue. The G-P calculator and a brief explanation of the G-P concept is accessible via the attachments below.
