This is a 3V active GPS glonass antenna intended for use with the GPSDO kit used with the USRP N200/N210 Series. The antenna can also be used for the USRP E310, which has an integrated GPS(SMA to SMB adapter needed).  A GPSDO locked to the GPS constellation can provide time synchronization within 50 ns of the global GPS standard and very high clock accuracy.
Small-sized, lightweight, easy mountable & ground-plane independent antenna with built-in LNA & SAW Pre-Filter, comes with 3m RG174 cable and SMA male connector.
Standards: GPS (1575.42 MHz) & GLONASS (1598 – 1606 MHz)
Supply Voltage Range: 1.5 – 3.6 V, high Active Gain 28 dB @2.7V, low power consumption 24.3 mW (typ.)
ESD protected up to 2 kV, dust & waterproof according to IP67
Possible applications: Telematics, Tracking & Tracing where high performance and detachable antenna is required, i.e. on cars, containers, trailers etc.
Note: please ensure antenna top side sees the sky as much as possible.
