The Scientific‑Atlanta D9828 is an 8‑port coaxial splitter module designed for cable television (CATV), broadband distribution, and headend/network signal distribution systems. Scientific‑Atlanta splitters are used to distribute RF signals from a single incoming feed to multiple downstream outputs with minimal signal loss. The D9828 is engineered for reliable RF performance in CATV headends, distribution frames, broadband amplifiers, and multi‑dwelling installations requiring balanced signal division with stable impedance.
