Abstract
In one embodiment, an antenna unit is provided that includes an antenna and a coax connector. The coax connector includes an inner conductor configured to contact a signal conductor of a coaxial cable and a ground contact configured to contact a metal shield of the coaxial cable. The coax connector is coupled to the antenna such that RF signals on the inner conductor are coupled to the antenna and such that RF signals sensed by the antenna are coupled to the inner conductor. The antenna unit also includes a non-volatile memory coupled to the coax connector such that the non-volatile memory can send and receive signals over the inner conductor. The non-volatile memory is configured to obtain operating power from a direct current voltage provided over a coaxial cable. The non-volatile memory has an identifier stored therein for identifying the antenna unit.
