OEM GNSS Antenna

Overview

HX-SE401A is a precision-tuned OEM GNSS antenna that supports GPS, GLONASS, BDS, and GALILEO, meeting the needs for high precision and multi-system compatibility. Its compact size, high reliability, customizable cable & connector, and easy integration make it an ideal choice for surveying and mapping, automotive applications, and scenarios requiring compact, high-performance antennas.

Key Features

Reliable Phase Center

The high precision HX-SE401A antenna features high gain, wide beam width as well as outstanding wide-angle circular polarization (WACP) performance. It exhibits a very stable phase center by adopting multipoint feeding technology, which ensures smaller phase center variation (PCV) for more precise positioning accuracy.

Strong Anti-Interference Performance

The advanced LNA (Low Noise Amplifier) of the antenna excels in improved signal filtering and out-of-band rejection by restraining unwanted electromagnetic interferences, providing strong anti-interference performance for consistent and reliable GNSS signals.

Compact and Reliable Antenna Structure

With a compact size of just Φ82×18.5mm and a weight of only 75g, HX-SE401A offers high precision, excellent consistency, and reliable electrical performance, guaranteeing stable positioning performance for many applications.

Precision-Tuned and Customizable

The standard version of the HX-SE401A comes with an MCX-C-JW connector, but the cable and connector can be customized upon request. OEM GNSS antennas are easily detuned by the local environment. Harxon offers custom tuning services for optimized integration into OEM end-user modules.
