MA-GNDM-685

GNSS L1/L2/L5 Conical Dome

The Midland Antennas MA-GNDM-685 is a conical dome-style, panel-mount antenna designed for comprehensive GNSS coverage, supporting global satellite navigation systems including GPS, GLONASS, Galileo, and BeiDou (BDS) across multiple frequency bands.

Optimized for high-precision applications, this antenna provides sub-centimeter-level positioning accuracy and features a stable, repeatable phase center, ensuring consistent results in demanding environments. The LNA offers powerful out-of-band suppression, reducing interference and improving signal lock retention.

Encased in a rugged, IP67-rated housing, the MA-GNDM-685 delivers reliable performance with high gain for stable signal reception in obstructed areas. The antenna connects via a TNC-K connector, providing secure and durable attachment.
