What type of wall port is referred to as MATV?

MATV stands for Master Antenna Television. This type of wall port is specifically designed for connecting coaxial cables that transmit television signals. MATV systems are used in buildings to distribute over-the-air television signals to multiple units using a single antenna system. The wall port provides a connection point for the end-user, allowing them to plug in their television or other monitoring devices to receive cable signals.

In contrast, VGA wall ports are used primarily for video signals, typically connecting computers to displays. RJ45 is a standard connector for network cables and is used for Ethernet connections, focusing on data transmission rather than television signals. CCTV connectors are dedicated to closed-circuit television systems, used for surveillance purposes. Thus, the MATV wall port serves a unique function, specifically for television signal distribution, making it the correct answer.
