The AJ979XF+ MAR is a high‑performance anti‑jam GNSS antenna engineered for mission‑critical positioning, navigation, and timing applications. It supports all major satellite constellations and frequency bands, delivering robust, reliable performance even in challenging RF environments.
Designed for marine and professional use, this antenna maintains accurate signal reception under interference and jamming conditions. Its advanced Low Elevation Angle Nulling Antenna (LEANA) technology suppresses unwanted signals near the horizon, while extended filtering ensures exceptional resistance to out‑of‑band interference.
With circular polarization across the full bandwidth and optimized gain at higher elevation angles, the AJ979XF+ MAR achieves superior signal integrity, excellent multipath rejection, and increased positional accuracy. Its dual‑channel low‑noise amplifier design ensures continued operation even when one channel is affected by interference.
Built for durability, the antenna features a rugged IP67‑rated enclosure, wide voltage input range, and integrated ESD protection. It is compliant with RoHS and REACH standards, making it suitable for deployment in demanding environments.
Ideal for marine systems, public safety, law enforcement, and precision timing applications, the AJ979XF+ MAR delivers consistent GNSS performance where reliability is critical.
