Installation Instructions
Step 1: Place the antenna on the mounting plane, aiming to 3 mounting holes, torque 5~10N.M is recommended.
Step 2: Opening holes is needed in the mounting bracket of antenna waterproof valve position , also ensure that the reserved space can get normal exhaust.
Step 1: Align the threads of the alignment mounting rod with the mounting holes underneath the antenna, and turn the antenna clockwise until the antenna is fully tightened against the mounting base, torque 10~15N.M is recommended.
Step 2: Then the connector head part is secured with heavy-duty tape or glue, preventing loosening during vibration process.
