NovAtel G5Ant-42AT1-A GPS/GLONASS L1/L2 ARINC Antenna with L-Band

NovAtel G5Ant-42AT1-A GPS/GLONASS L1/L2 ARINC Antenna with L-Band

The NovAtel G5Ant-42AT1-A is a multi-constellation active GNSS antenna supporting GPS/GLONASS L1, L-Band, GPS/GLONASS L2 bands with an ARINC form factor.



The G5Ant-42AT1-A GPS/GLONASS L1/L2 ARINC antenna with L-Band is part of the G5Ant-42XXX-A product family of multi-frequency GNSS antennas. This G5 antenna operates in five frequency bands and includes support for GLONASS L1, GPS L1, L-Band, L2 GLONASS and L2 GPS. The baseplate is compatible with ARINC 743 mounting hole and footprint requirements. An O-ring seal between the antenna and your platform ensures easy installation. The “-A” version of G5Ant-42XXX locates the connector output along the centerline of the product baseplate.

This product available in passive and active (amplified) configurations. The active configurations offer 2-stage integrated bandpass filtering for high out-of-band rejection and limiter diodes to protect sensitive receiver electronics. The passive configurations are best suited to applications where the antenna is located close to the GNSS receiver and offers the lowest insertion loss to minimize the noise figure of your system.
