Chapter 2: Installing the system

Placing the antenna
GPS receivers
Good quality GPS receivers will work properly very close to the antenna -
typically down to one meter outside the main beam, and down to a few meters
inside the main beam. However, simple GPS receivers with poor frequency
discrimination could be affected at longer range (typically 10 m). It is always
recommended to test the GPS performance before the installation is finalized.
VSAT systems
For optimum performance we recommend a minimum distance of 3 meters
from the BGAN antenna to VSAT antennas.
Other transmitters
Minimum distance to transmitters
on page 142 in Appendix B for minimum
recommended distance to transmitters in the frequency range below
1000 MHz.
Other precautions
Do not place the antenna close to a funnel, as smoke deposits are corrosive.
Furthermore, deposits on the radome can degrade performance.
