Timing2000 Antenna

The Oncore Timing2000 Antenna, targeted at GPS timing applications, is designed foruse with the Motorola’s Oncore receivers as well as many GPS receivers from othermanufacturers.

• 25dB Active AntennaHigh performance without interference• 5 Volt operation• 26mA typical current consumption• High strength direct mount• <1.5dB typical noise figure• 40dB minimum filtering at +/- 50MHz

Consuming only minimal five-volt power, this new antenna design reflects Motorola’shigh standards for performance while operating in the presence of electromagnetic
interference. GPS signals are received by the antenna, amplified within the antennaassembly, and then relayed via cable to the Oncore receiver module for processing.
Built to withstand weather

The conical radome housing, UV-resistant material and a tubular mounting nut
specially designed for ease of weatherproofing, assure superior performance while
operating in the world’s challenging weather environments.
