345 | | A GPS antenna assembly is provided, and connected to the IDU, to provide a stable and precise timing source to the base station. [[BR]] |
346 | | |
347 | | The antenna assembly is connected to the NEC IDU using a 50-ohm coax, that carries the received signal to the IDU, and power to the antenna assembly. [[BR]] |
