Manufacturer: | Categories: ,

The NovAtel G5Ant-3AMT1 is a multi-constellation GNSS antenna with circular footprint.



The NovAtel G5Ant-3AMT1 multi-constellation GNSS antenna with circular footprint is part of the G5Ant-3XMXX family of multi-frequency GNSS antennas. This G5 antenna operates across five frequency bands and includes support for GLONASS L1, GPS L1 plus E1 Galileo, L-Band plus E6 Galileo and B1 BeiDou, L2 GLONASS and L2 GPS plus B2 BeiDou. This product family is designed to the standard Fixed Reception Pattern Antenna (FRPA) mounting footprint and includes magnets recess mounted into its baseplate for easy installation and testing.

The product family is offered 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.
