Figure 19: AN-2004T 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)
