Description: This tri-band GNSS antenna is ideal for GPS L1 GLONASS L1 and Beidou B2 reception. At 45x45mm it is a large ceramic antenna with an incredible 38dB LNA gain.This antenna works well with the GPS-RTK providing reception of Beidou satellites where other more basic GPS antennas cannot. We’ve chosen to have the antenna manufactured without an enclosure to decrease the weight (45g including cable) making this antenna more ideal for rover and quad-copter applications. Additionally the cable length has been reduced to 1m to reduce weight and to make a more clean installation.We recommend this antenna for RTK use when combined with the ground plate. This antenna is ideal for advanced raw RTK and post-processed measurements of GPS GLONASS and Beidou constellations.Antenna is terminated with a standard SMA connector.
