Quectel YEMA300QXA Antenna

Quectel YEMA300QXA Antenna is an adhesive mount 3-in-1 combo antenna optimized for 4G, Wi-Fi^®, and GNSS networks. This antenna is available with connection via 3 cable lengths ranging from 300mm to 5000mm (compatible with ECE-R118 cables). The YEMA300QXA antenna measures 143.73mm x 51.33mm x 15mm, and can integrate 4G, GNSS, and Wi-Fi antennas. This antenna offers high isolation between antennas to avoid self-interference. The YEMA300QXA antenna is designed to provide a stable, high-speed data connection for 5G and GNSS applications and is compatible with RM520x series modules. The YEMA300QXA antenna is RoHS compliant, offers maximum durability, and can be used in harsh environments.

The YEMA300QXA antenna is ideal for applications that require a discrete, low-profile, screw-mount, omnidirectional, and easy-to-install antenna. Typical applications include HD video over LTE, first responder and emergency services, transportation and automotive, automotive vehicle tracking, and telematics.
