The function of a suction cup antenna is to radiate and receive radio waves. It is fixed in place by a suction cup base to prevent displacement or damage. Thanks to its stable base structure, suction cup antennas are widely installed on vehicles.
Working Principle of Antennas
During transmission, high-frequency current is converted into electromagnetic waves. During reception, electromagnetic waves are converted back into high-frequency current.
Installation Notes for Suction Cup Antennas
The surrounding environment greatly affects antenna performance. It should be installed in an open area without tall building obstructions and strong electromagnetic interference, so as to ensure stable long-distance signal transmission and reception.
When used with wireless modules, follow the guidelines below to achieve optimal communication distance:
-
Keep the antenna away from the ground and surrounding obstacles as much as possible.
-
Straighten the feeder cable during installation, and attach the suction cup base firmly to a metal surface.
