Applications

The Datum Bullet II GPS outdoor antenna system was widely used in precision timing and frequency reference applications — including telecommunications network synchronization, broadcast facilities, and financial network time servers — where a GPS-disciplined oscillator provided a highly accurate time and frequency reference. This antenna cable connects the rooftop or exterior-mounted Bullet II GPS antenna to the indoor GPS receiver or timing unit. The 50-foot length gives enough reach for installations where the antenna is mounted on a roof edge or antenna mast and the receiver is housed in an equipment room below. Coaxial GPS antenna cables of this type are still used wherever legacy Datum or Symmetricom GPS timing receivers remain in service, which is common in older telecom and broadcast infrastructure.
