Key Features

Integrated Design and Compact Form Factor

The compact smart antenna with IP67 rated enclosure , weighing ≤40g and measuring Φ48*H38mm, greatly reduces the weight of UAVs and features low power consumption.Additionally, the GNSS antenna and module are well compatible with each other, simplifying the development process .
Precision-Tuned OEM GNSS Antenna

HX-MR401A is integrated with Unicore’s full-constellation full-frequency RTK positioning module UM980, which integrates RF, baseband and high precision algorithm. The antenna provides excellent axial ratios, enables excellent multipath mitigation and a very precise phase center.
High Performance RTK Positioning Module

Integrated with Unicore’s full-constellation full-frequency RTK positioning module UM980, which integrates RF, baseband and high precision algorithm, it can track multiple frequencies of all GNSS systems, enabling high-precision RTK positioning.
Strong Anti-Interference Performance

HX-MR401A is capable of offering superior positioning performance in challenging environments. The antenna equips a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance, and the module features 60 dB narrowband anti-jamming.
