Q: Can this antenna be mounted on a non-metallic surface?
A: Yes, it will work. However, for omnidirectional antennas of this type, a metal ground plane (like a cabinet top) often helps optimize the radiation pattern.
Q: Is it suitable for extreme outdoor weather?
A: The radome is weather-resistant, but we recommend applying waterproof tape or a rubber gasket around the base during installation for complete environmental sealing.
