The following parameter specifies the filename for an antenna pattern file that determines the gain provided by each pattern at each angle.
Note: This file is an option only for 3-dimensional antenna patterns.
#
ANTENNA-ELEVATION-PATTERN-FILE ./default.antenna-elevation
#
The first line in the Elevation Pattern file indicates the number of patterns to follow:
NUMBER-OF-RADIATION-PATTERNS <numPatterns>
The remaining lines in the Elevation Pattern file are of the following format:
<patternIndex> <angle> <gain>
This is where patternIndex is the pattern number, from 0 to (NUMBER-OF-RADIATION-PATTERNS – 1), angle is in degrees where 0 is perpendicular to the antenna, and gain is the antenna gain for this pattern, at this angle, in dBi.
