A 4-way RF splitter is a device that divides a single radio frequency signal into four different signals for use in broadcast and telecommunication systems. It is made to work with coaxial cable and F-type connectors and typically has a frequency range of up to 1 GHz or higher. Additionally, a 4-way RF splitter might have features like an integrated amplifier to strengthen the signal or surge protection to guard against power surges and lightning strikes. It is a helpful device for dispersing a single RF signal to numerous components in a communications or broadcast system, and it can facilitate the setup and administration of these systems.
