Radiation Pattern
Figure 83: 82-001017-0001LF Radiation Pattern
Optimal antenna performance is realized at
elevations greater than 30º.

There is a 10dB variation between 0º and 90º
elevation (factor 10x); therefore, lower
elevation satellites are always more difficult to
track.

There is a 5dB variation between ~35º and 0º
elevation (factor >3x)
