GPS Antenna for Timing & Stationary Application 497-04006-00



Item Number : 497-04006-00
Combining the most innovative concept with precision manufacture, we release this latest GPS antenna—497-04006-00.
With the compact polycarbonate radome enclosure and the waterproof/weatherproof physical construction, SA-300 is deliberately designed for both navigators and researchers who often need to use GPS in harsh environments, such as strong shock or vibration, fierce wind, and even continuous exposure to water and sunlight.
Additionally, 497-04006-00’s stainless pole mount not only enables antenna to receive GPS signals steadfastly, but also enables the cable to be threaded, protecting itself from environmental damage. Both of the industrial standard TNC connector & 1”-14 straight thread perfectly fit the typical marine mount, enhancing the multifunction and application for 497-04006-00. Furthermore, through the inventive integration of dual amplifiers & dual filters (saw filter + bandpass filter), 497-04006-00 provides excellent resistance to RF signal interference without compromising its gain, which helps ensure stable performance even in RF signal-jamming environment.
497-04006-00 is an active GPS antenna with high gain of 27 dB & low current of 27mA, supporting RG-58 A/U cable as long as 50m.
Given the aforementioned features, we believe 497-04006-00 to be your most reliable companion for timing and stationary applicati on
