    DGPS224(JLR-4341) 3.3 Installation Procedure 3.3.1 Installation of the Sensor The sensor base contains 1 inch 14UNS-2B screw holes. It can be attached to poles with cut male screws, or off-the-shelf adapters. (1) When performing attachment, always hold and turn the sensor base. Holding and turning the radome may result in a large amount of force applied at the junction of the base and the radome, resulting in damage to the sensor.
