The GPS antenna must have a clear view to approximately ten degrees of the horizon in
all directions. Surrounding obstacles such as trees, buildings, etc should not exceed a
20 degree elevation angle. Blockage due to buildings, mountains, etc. should be less
than 50% of the sky.
RF Interference
To avoid the influence of reflected waves, the antenna must not be installed less than 2
m (~6.5 ft) away from metallic objects having dimensions greater than 0.2 m (~8 in).
Grounded metal structures may block or reduce the signal from a satellite.
To minimize susceptibility to radio interference, the GPS antenna should generally be
located at least 1 m (~3.25 ft) away from antenna systems for any another high
frequency system (e.g., microwave, GSM, CDMA, 3G). Avoid mounting the GPS
antenna within the main beamwidth of any active (radiating) antenna system.
