The JS-HAC26A is a four-arm helical active antenna supporting GPS, BDS, GLONASS, and Galileo dual-frequency signals. Built on a cylindrical ceramic substrate with four curved metal wires, it combines the features of Zapper and vertical antennas. This innovative design delivers strong gain, excellent radiation patterns, and full 360° reception. Unlike microstrip patch antennas that require flat placement, the JS-HAC26A ensures reliable signal acquisition from any orientation once integrated into navigation devices.
