NAME	Name of the antenna. Must be the same as the filename
FREQUENCY	Design frequency of the antenna in MHz
GAIN	Antenna gain followed in dBd (ref. to dipole)
TILT	Indicates whether the antenna is to be electrically or mechanically tilted. Set to either ELECTRICAL or MECHANICAL.
COMMENT	A single line of comments. Includes the date of measurement and any other additional information.
HORIZONTAL	The number "n" following indicates that the next "n" lines of data correspond the horizontal radiation pattern.
VERTICAL	The number "n" following indicates that the next "n" lines of data correspond the vertical radiation pattern.

The Antenna values are in the form:
Angle Loss in dB

Where the angle must be from 0 to 360 degrees. The interval may vary but must not be smaller then 0.1 degrees.
The diagrams below should help clarify the meaning of each field:
