## Overview
The YEMA300QXA is a 4G, Wi-Fi and GNSS adhesive mount 3-in-1 combo antenna optimized for 4G, Wi-Fi and GNSS networks. With dimensions of 143.73 mm x 51.33 mm x 15 mm, the antenna can integrate a variety of antennas, such as 4G, GNSS and Wi-Fi antennas. The antenna is available with connection via 3 cable lengths from 300–5,000mm (compatible with ECE-R118 cables), terminated with SMA male connectors.

Ideal for applications where the antenna is required to be discrete, this low profile, screw mount omni-directional antenna is easy to install, with maximum durability assured thanks to its IP67 rated enclosure.

The YEMA300QXA is made up of 3 antennas, with 1 x 4G antennas covering 698–960 MHz and 1700–2700 MHz, 1 x Wi-Fi antennas covering 2400–2500 MHz and 5150–5850 MHz and 1 x GNSS L1 antenna covering 1559–1606 MHz. In the meantime, this product also offers high isolation between antennas to avoid self-interference. All in all, this unique product is designed to provide stable and highspeed data connection to 5G and GNSS applications. The YEMA300QXA can be used in harsh environments thanks to its robust PC enclosure.

Typical applications for the YEMA300QXA include HD video over LTE, first responder and emergency services, transportation and automotive, automotive vehicle tracking, and telematics.
