An antenna rotator includes a housing having an access port disposed therethrough. Positioned within the housing and proximate to the access port is an interface connector. The interface connector provided by the housing is configured to be removably attached to a module connector provided by a detection module, which may include a sensor for detecting a position of an encoder that is rotated by a motor drive within the housing. As a result, the detection module, which is highly susceptible to electrical damage from lightning, can be conveniently accessed and replaced.
