High performance 1 GHz Digital Splitters are used for splitting a single coax line into 2, 3, 4, or 8 lines. These splitters are designed for applications that operate in the 5 MHz to 1 GHz range, which include: 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.For best system performance, choose a splitter with the minimum number of outputs for your application requirements. This minimizes attenuation/signal weakness to each of the ports and provides the strongest signal to each individual device.Install splitter as close as possible the devices receiving the split cables. This minimizes the length the split (attenuated) signal needs to travel.
