Nokia 472748A.101 FYGB is a high-performance GPS/GLONASS dual-mode receiving antenna compatible with Nokia NSN base stations. Supporting both GPS and GLONASS satellite systems, this product provides precise positioning services for base station equipment, serving as a key supporting component to ensure the positioning accuracy and communication stability of base stations in wireless communication networks. Based on publicly available market information, the detailed introduction is as follows:
The core advantage of this antenna lies in its dual-mode positioning support, enabling simultaneous connection to both GPS and GLONASS satellite systems. Compared with single-mode antennas, it can receive more satellite signals, significantly improving the positioning accuracy and stability of base stations while avoiding positioning failures caused by signal interruptions of a single satellite system. Adopting a mushroom-shaped design, the product integrates a signal receiving module and needs to be installed in an unobstructed outdoor area of the base station to ensure optimal satellite signal reception. It is powered by an integrated power and data cable, adapting to the power supply and data transmission requirements of the base station. Additionally, it boasts exceptional environmental adaptability, with an operating temperature range of -40℃ to 85℃, enabling it to withstand extreme weather conditions such as high temperatures and severe cold. Furthermore, the product features fixed dimensions (95mm in depth, 72.5mm in height) and a lightweight design (only 154g), facilitating outdoor installation work.
As a dedicated supporting device for Nokia NSN base stations, this antenna strictly complies with the hardware interface and communication protocol standards of Nokia base stations. During actual assembly, there is no need to modify the system architecture or circuit layout of the original base station; it can be directly connected to the core control module of the base station for immediate use, demonstrating strong adaptability. Meanwhile, its interface specifications are compatible with other Nokia base station accessories in the same series, enabling seamless connection during base station upgrades or accessory replacement, and reducing the workload of equipment compatibility debugging.
This antenna is widely used in Nokia NSN base stations worldwide, suitable for base station construction in various scenarios such as dense urban areas, open suburban regions, and remote mountainous areas. In urban base stations, its precise positioning function can assist in optimizing signal coverage and ensuring communication quality for high-density users. In suburban and mountainous areas where signals are prone to terrain obstruction, its dual-mode receiving capability can effectively capture satellite signals, preventing base station positioning deviations and ensuring stable signal transmission in the region. Additionally, it serves as a common spare part for daily base station operation and maintenance. When the original antenna experiences issues such as signal attenuation or damage, this product can be used as a replacement to quickly restore the positioning function of the base station.
