3. Update the following parameters as needed:
Parameter Description
Antenna Azimuth Synopsis:  A number between 0 and 359
The angle between true north and the perpendicular projection of the subscriber unit
onto the horizon.
Antenna Downdrift Synopsis:  A number between -90 and 90
The degree of beamtilt compared to the horizon. A negative value means the antenna is
tilted up (above horizontal).
Gain Synopsis:  A number between -127 and 128
The antenna's peak gain, measured on the decibel logarithmic scale (dBi).
Antenna Type Synopsis:  { Omni, Directional }
Default:  Omni
The type of antenna used by the subscriber unit. Options include:
• Omni – Omni-directional antenna
• Directional – Directional antenna
Beam Width Synopsis:  A number between 0 and 360
The width of the antenna's beam, measured in degrees (°), on the horizontal-plane.
A value of 360 means the antenna has an omni-directional radiation pattern in the
horizontal plane.
