Overview
The CommScope CBC78T-DS-43 twin diplexer is an outdoor-rated passive RF combining and splitting device that separates two frequency bands for simultaneous transmission on a single antenna feed path. The 4.3-10 female connectors deliver improved passive intermodulation (PIM) performance compared to legacy N-type or 7-16 DIN connectors in a reduced form factor. Automatic DC switching with DC sense enables remote electrical tilt (RET) and antenna control over the coaxial line. Convertible mounting brackets and stackable hardware provide installation flexibility for pole and wall mounting in cellular base station, DAS, and outdoor wireless deployments.
