This file contains the horizontal and vertical radiation pattern of a antenna depending on the version of data.

There are 3 types of .ant files that can be used by Radio Mobile.

1. Antennapattern file with only the horizontal plane of the radiation pattern.
   This file is referred to as 'version 1'. See 'Antenna .ant format (V1)'
2. Antennapattern file with the horizontal plane and 180 degrees (+90 to -90 degrees) of the vertical plane of the radiation pattern.
   This file is referred to as 'version 2'. See 'Antenna .ant format (V2)'.
3. Antennapattern file with both horizontal- and vertical plane in full 360 degrees.
   This file is referred to as 'version 3'. See 'Antenna .ant format (V3)'

From version 9.6.5 Radio Mobile supports both horizontal- and vertical- plane in antenna patterns. It is advised to use the V3 antenna patterns for better simulation results.
