Quectel YEMA301J1AM combo antenna

For applications requiring enhanced cellular performance, Quectel’s YEMA301J1AM integrates dual 4G antennas and a GNSS antenna in a compact 3-in-1 design. Optimised for field operations and fleet management, automotive telematics, smart city infrastructure, utilities and HD video streaming applications, the product offers robust connectivity while maintaining a discreet installation profile.

Supporting 4G operation in the 698–960 and 1710–2690 MHz bands and GNSS coverage from 1559–1606 MHz, the device features high inter-antenna isolation to minimise self-interference and maximise performance in demanding environments. It delivers efficiency of up to 73.2% for 4G DIV-FS and up to 45.3% for GNSS-FS, together with GNSS LNA gain of approximately 16 dB. Its rugged IP67-rated enclosure enables deployment in challenging outdoor conditions, while RoHS compliance supports environmental and regulatory requirements.
