The AJ977XF from Tallysman is a Triple-Band Anti-Jam GNSS Antenna. This antenna is designed to mitigate interference and jamming signals broadcast from near ground-based transmitters. It includes a Low-Noise Amplifier (LNA) which requires a DC supply from 2.5 to 16 V and consumes 62 mA of current. The LNA provides a gain of 40 dB and has a noise figure of 2.5 dB. This antenna supports GPS/QZSSL1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, and NavIC-L5 constellations. Regional augmentation services such as WAAS (North America), EGNOS (Europe), MSAS (Japan), GAGAN (India), and high-precision L-band correction services are also supported by this antenna.
The AJ977XF provides wideband suppression of 20 dB across all GNSS band signals received at an elevation angle from 0° to 15°. It is available in an IP67-rated weatherproof enclosure that measures 90 (Dia.) x 180 (H) mm with TNC (female) connectors and is ideal for all mission-critical positioning, navigation and timing applications.
