Product Description:

The JF-JH702 is a dual-frequency OEM GNSS antenna with exceptional anti-interference performance, designed for challenging electromagnetic environments, including high-power and strong multipath scenarios. Its bottom-mounted vertical and horizontal polarization suppressors, coupled with advanced pre-multiple filtering, effectively suppress out-of-band noise and multipath signals, significantly enhancing anti-interference capabilities. It is ideal to be integrated into applications requiring both interference mitigation and high-precision positioning, such as portable or large mobile ground equipment and high-altitude drones. It also supports static millimeter-level positioning with multi-brand boards.
