About This Part
The COMBA SBC-21-SAME BAND COMBINER 2100MHZ is a critical passive component in modern wireless communication networks. Its primary function is to efficiently merge multiple RF input signals that operate within the same 2100MHz frequency band into a single output port. This capability is vital for streamlining antenna deployments, reducing site complexity, and enabling multiple services or carriers to share common infrastructure, thereby optimizing space and operational costs. Common applications for the SBC-21 include cellular base stations, distributed antenna systems (DAS), and in-building wireless solutions where efficient signal aggregation is required. For instance, it can combine signals from different 2100MHz sectors or technologies (e.g., LTE Band 1, UMTS Band 1) before feeding them into a shared antenna. Comba is a reputable manufacturer, and their combiners are engineered for high performance, featuring characteristics such as low insertion loss to preserve signal strength, high isolation between input ports to prevent interference, and excellent passive intermodulation (PIM) suppression for clear signal transmission. Revo Distribution Limited provides refurbished COMBA SBC-21 units to meet the demand for reliable and economical telecom infrastructure components. By offering tested and certified used equipment, Revo empowers B2B clients, including network operators and system integrators, to enhance their network capacity and coverage at a reduced cost. This commitment to sustainable and value-driven solutions helps our partners achieve their operational goals while extending the lifecycle of high-quality telecom assets.
