The Splitter is designed for applications that operate in the 5MHz to 1GHz range, which includes digital/HD cable TV, broadcast (over the air) TV, CCTV, and other general purpose coaxial cable splitting requirements. All splitters include an internal printed circuit board design inside of a nickel plated zinc die cast housing which helps to improve overall splitter performance in return loss, insertion loss, and port-to-port isolation measurements, resulting in a stronger, cleaner signal with more protection from outside signal interference. All 1 GHz splitters have a soldered back (not glued) for improved EMI/RFI performance. Machine formed threads on the F ports allow for smooth connector mating. Splitters include a grounding screw port for attaching ground wires and two user accessible mounting holes.
