The GL9X1AX-TRB from PCTEL is a GNSS Multi-Band Antenna with multiple ports for 4G LTE and 802.11ac MIMO applications. The antenna has four 4G LTE ports that support carrier aggregation for high-speed data transmissions needed in dense RF environments, such as public safety broadband networks. It also has four Wi-Fi ports for dual-band 802.11ac Wi-Fi MIMO connectivity and one port for PCTEL&rsquos proprietary high-rejection multi-GNSS technology for high precision tracking and asset management. It delivers a gain of up to 4.4 dB with an efficiency of over 27% and can handle an input power of below 25 watts. This dual-carrier antenna is designed to meet the requirements of increasingly complex RF communication systems in transportation and IIoT applications.
