L1 GNSS Active Outdoor Receive, Omni-directional Antenna
Global Foxcom’s L1 GNSS Active Outdoor Receive Antenna captures GPS L1, GLONASS G1, Galileo E1, and BeiDou B1 signals at the outdoor receive point of compatible GNSS repeater systems. The integrated low-noise front-end filtering reduces unwanted RF signals before transmission through the coaxial connection. The IP67-rated enclosure supports outdoor installation in exposed environments requiring reliable GNSS signal reception.

Which GNSS signals are supported by this antenna?
The antenna receives GPS L1, GLONASS G1, Galileo E1, and BeiDou B1 signals across the 1.55–1.61 GHz frequency range. Supporting multiple satellite navigation constellations enables integration with GNSS repeater systems designed for L1 signal distribution.
How does the front-end filter address nearby RF interference?
The integrated front-end filter reduces unwanted RF energy. This provides additional interference immunity when the antenna operates in locations with nearby radio transmissions or other RF activity.
Why is RHCP polarization used for GNSS signal reception?
GNSS satellites transmit signals using right-hand circular polarization (RHCP). The antenna’s RHCP design matches the polarization characteristics of GNSS signals, supporting reception of GPS L1, GLONASS G1, Galileo E1, and BeiDou B1 signals.
How does the antenna support outdoor GNSS signal acquisition?
The antenna is designed for outdoor receive locations where GNSS satellite visibility is available. Its IP67-rated enclosure, omnidirectional receive pattern, and −40°C to +85°C operating temperature range support deployment in exposed environments requiring consistent satellite signal collection.
