Antenna .ant format (V1)

Prior to version 9.2.3 Radio Mobile only supports horizontal plane antenna patterns.

It is advised to use the V3 antenna patterns for better simulation results.

The following image displays the Horizontal plane of the antenna pettern with a Yagi that is vertically polarised

Horizontal plane of a antenna

General description of the file.

In this file only the horizontal plane of the radiation pattern is described. In 1 degree steps the attenuation in dB with respect to the gain of the antenna is specified. All individual steps from 0 to 359 degrees is described.
