• Antenna Cable TV: This indicates that the device is suitable for both antenna TV signals and cable TV signals, making it versatile for various signal sources.
• Professional Digital Signal System: This implies that the device is designed for use in professional-grade signal distribution systems and is capable of handling digital TV signals, including high-definition television.
• CATV 2X4 Splitter Amplifier: This identifies the device as both a splitter and an amplifier. “2X4″ suggests that it has two input ports and four output ports, meaning it can take a signal from two sources and distribute it to four devices or endpoints. The “splitter” function divides the signal, and the “amplifier” function boosts the signal strength to maintain quality.

Devices like this are useful for distributing TV signals within a building or system, ensuring that multiple televisions or devices receive a strong and clear signal. They are commonly used in residential and commercial settings to extend the reach of cable TV or antenna TV signals.
