Abstract

In various exemplary embodiments, an antenna assembly is configured for installation to a vehicle body wall having a mounting hole. The antenna assembly generally includes an antenna base configured to be disposed along an external side of the vehicle body wall. An electrical connector is coupled to the antenna base such that, when the antenna base is disposed along the external side of the vehicle body wall, the electrical connector is accessible from inside the vehicle. Accordingly, an installer (from inside the vehicle) may thus plug a communication link into the electrical connector to thereby allow the communication link to communicate signals received by the antenna assembly to another device.
