Base Antenna Radiation Pattern

Figure 117: Base GNSS Antenna Radiation Pattern

Optimal antenna performance is realized at elevations greater than 35º.

There is an 11dB variation between 15º and 90º elevation (factor >10x); therefore, lower
elevation satellites are always more difficult to track.

There is a 9dB variation between ~35º and 0º elevation (factor >8x)
