High-Precision Multi-Band Active GNSS Antenna - L1/L2/L5

This high-precision multi-band active GNSS antenna supports GPS, BeiDou, GLONASS and Galileo positioning systems across multiple L1/L2/L5 frequency bands. Its built-in 37dB low-noise amplifier boosts received satellite signals before they reach your GNSS receiver.

The antenna uses a quadrifilar helical design with right-hand circular polarisation (RHCP) and wide-angle coverage. This design improves reception of satellites at lower elevation angles, making it well suited to RTK positioning, surveying, mapping and other high-precision GNSS applications. Connection and DC bias power are provided through the SMA-Male connector.

This antenna covers the main multi-band GPS, BeiDou, GLONASS and Galileo frequencies used for high-precision positioning. If your GNSS receiver also supports L-Band correction services, see our Multi-Band GNSS Antenna with L-Band Support instead.
