Description
Product Overview
The Calian AC4990SXF is a low profile surface mount full band GNSS antenna designed for high accuracy positioning in vehicles, autonomous systems, robotics, precision agriculture and industrial equipment. Built on Accutenna 4 technology, it supports multi constellation GNSS reception across full band signals, helping deliver stable positioning performance for RTK, PPP and correction based systems. Unlike the pole mounted AC4990PXF, the AC4990SXF is designed for surface installation using 4 x M3 screws, magnetic mounting or adhesive tape, making it better suited to vehicle roofs, machine housings and equipment enclosures.
