COMMSCOPE CBC781921WT-DS E15V90P4703 QUAD T 700/850/PCS/AWS-WCS DC SENSE T268738

The CommScope CBC781921WT-DS (E15V90P4703) is a high-performance Twin Quadplexer designed for co-siting applications. It enables antenna and feeder sharing by combining four frequency bands (700-750 MHz, 850 MHz, PCS, and AWS-WCS) into a common RF path. This "Twin" model contains two complete, independent quadplexers in a single rugged housing, making it an ideal space-saver for crowded tower configurations. This Quadplexer, meaning it manages four distinct frequency bands simultaneously, is a "Legacy-to-Modern" bridge component: it was officially discontinued by CommScope in 2020 but remains in high demand for repairs and maintenance of existing 4G/LTE macro sites that haven't yet been fully converted to the newer 4.3-10 connector standard.
