More about RF Modulators

Modulation in its most basic definition is the mixing of two sinusoidal signals. The RF modulator takes an input signal and outputs a modulated signal to be transmitted as a video channel to any number of connected TVs. RF Modulators are used to distribute video in widely diverse installations, including stadiums, arenas, office buildings, college campuses, houses of worship, sports bars, and restaurants
