Digital channels that are generated from this device can be scanned and tuned by most TV and set-top box ATSC/OTA tuners. Equipped with a front panel display and menu navigation buttons, settings such as RF channel number, virtual channel number, and RF output level can be configured without the use of a computer. The modulator can also be managed over a local network via the built-in ethernet port.

Popular applications for this device include commercial environments such as restaurants, bars, hotels, and office buildings needing to distribute an HDMI video source over the coax cable network along with ATSC TV signals from an over-the-air TV Antenna. The Channel Master ATSC HD Modulator includes a built-in coaxial pass-through feature which enables the ability to combine the modulated channel with an antenna signal without the use of an external combiner.
