Abstract
Abstract A system is provided with a directional antenna having first and second antenna patterns oriented around an antenna boresight direction. The antenna boresight is oriented in a direction corresponding to a play determinative line on a playing field. Signals are emitted firm a playing object, used as a ball and detect using the two antenna patterns. Comparison of the detected signals provides an output indication when the playing object crosses the play determinative line.
