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.
3.3.6 Other transmitters
Minimum Recommended Distance to Transmitters.
Appendix B for minimum recommended distance to transmitters in the
frequency range below 1000 MHz.
3.3.7 Other precautions
Do not place the ADU close to a funnel, as smoke deposits are corrosive.
Furthermore, deposits on the radome can degrade performance.
