Channel Master CM-3212HD 2-Port Splitter 75 ohm

Two-Port Signal Splitter for Dual-TV Setups

This 75 ohm splitter takes a single antenna feed and delivers it to two televisions, making it practical for households that want the same over-the-air channels on more than one screen without running a second cable from the roof. The all-metal housing and weather-sealed ports allow indoor or outdoor mounting.

Insertion Loss and Frequency Limits of Passive

A passive two-way divider halves the signal power at each output, which on a 75 ohm coaxial network translates to roughly 3.5 dB of insertion loss per port; weak fringe signals that are already near the tuner threshold may drop out after the split. The specified bandwidth covers current ATSC 3.0 and 4K broadcast frequencies, but the device does not amplify, so it cannot recover losses from long cable runs or additional splitters downstream.

Power Passing on All Ports Determines Preamplifier

Because every port passes DC voltage, a single mast-mounted preamplifier or distribution amplifier can be powered through either output without a separate injector, simplifying installations where the amplifier sits at the antenna. Buyers who need to isolate DC between ports or who require more than two outputs should choose a different splitter topology.
