Q: Can it be used on non-metallic surfaces?
A: While it will stay upright, suction cup antennas perform best when attached to a metal ground plane, which helps as a reflector for the signal.
Q: Is this antenna waterproof?
A: The antenna is designed for outdoor use; however, for long-term extreme weather exposure, it is recommended to protect the connector area.
