Base Antenna Radiation Pattern

Figure 66: Base GNSS Antenna Radiation Pattern

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

There is a 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)
