A vehicular multi-band antenna is adapted to receive signals in the AM/FM bands and to receive and transmit signals in a significantly higher frequency band such as that used for cellular telephone. The antenna is provided with a base section fixedly mounted on the vehicle and a removable antenna mast section removably received in the base section.

Connector assembly for fixed triband antenna

A retractable motorized multi-band antenna is adapted to receive signals in the AM/FM bands and to receive and transmit signals in a significantly higher frequency band such as that used for cellular telephone. In order to transfer the coaxial input signal to an output coaxial connector, a slip ring connector is provided. The slip ring connector is impedance matched to the antenna to create low VSWR at RF frequencies.
