Product OC: YECN028AA Version: 0.1 Date: 2026-06-11 Status: Preliminary Product Name: 4G Terminal Mount External Dipole Antenna Key Features: Frequency Band: 900–960 MH Dimensions: 225 mm × 54.5 mm × 13 mm Efficiency: Up to 74.2 %(FS) RoHS and REACH Compliant IP66(housing) Antenna Datasheet Antenna Services YECN028AA Datasheet Antenna_Datasheet 1 / 26 Overview YECN028AA is a 5G external antenna measuring 225 mm × 54.5 mm × 13 mm. This ultra-wide-band 5G antenna provides broad coverage from 410–470 MHz, 617–960 MHz, 1427–6000 MHz whilst offering backward-compatibility to support 4G/3G and 2G networks as well as LTE Cat-M and narrowband IoT (NB- IoT). The antenna is terminated with SMA Male connector. Ideal for applications where the antenna is required to be discrete, this low profile, terminal mount omni-directional antenna is easy to install with maximum durability assured thanks to its IP66 rated, PC enclosure. The YECN028AA can be used in harsh environments thanks to its robust UV resistant (UL 746c f1) and flame resistant (UL 94 V-0) enclosure. The antenna is designed as dipole type to work with various GND plane sizes or in free space for ease of integration with a hinged SMA Male connector to achieve the optimum position. Hinged structure helps to avoid other antennas or objects by rotating to different directions when mounted on terminals. This omni- directional antenna is ideally suited for access points, terminals and routers, high speed video, real-time streaming, public transportation, offering great performance with its high gain and efficiency. Typical applications include: ⚫ Access points, terminals and routers ⚫ High speed video ⚫ Real-time streaming ⚫ Public transportation Quectel provides comprehensive antenna design support such as simulation, testing and manufacturing for custom antenna solutions to meet your specific application needs. We have regional R & D centers to offer quick response to meet your requirements. Please contact our sales & FAEs if you have any requests.
