Overview

The Channel Master ATSC HD Modulator is a professional grade encoder/modulator designed for commercial and residential installations. The ATSC HD Modulator converts a video signal from HDMI format to a Digital ATSC (Coax) format.

The digital channel is user-selectable (2-99) then output via the coaxial RF output on the back of the device. 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.

Best value in this category

Works well and very stable.

Wish it encoded in 5.1 instead of downmixing/omitting to stereo

None of the ATSC 1.0 modulators encode more than 2 audio channels, including this one, even though they encode in AC3. I think it would require a license from Dolby.

I also wish it had 4K HDMI pass-thru. The idea being you could put this modulator in between your Apple TV and living room TV and still watch main TV in 4K while transmitting 1080p to the other TVs in the house.

Great value!

It works great, and the price is the best that I have found. It's simple to set up, and compatible with older TVs. I have tried more expensive modulators that didn't perform as well.

Works in my unusual environment.

I've lived a floor beneath mobile phone antennas for the area for over a decade, and now in directly line with a newish emergency responder pole to those same antennas. I've always struggled to get good OTA signal, and had to resort to purchasing cable TV for the summer months a few years off and on until demand dropped. Things changed drastically for the worse when 5G came out. I'm glad I bought this modulator. I probably works the best at tuning of all my OTA devices. I had an older laptop with a tuner card that comes close, but it was for emergencies only, as I'm used to having TV on my computers in all three rooms of my apartment through a HDHomerun, so adjusting to lugging the laptop wasn't going to work. My output from the ATSC modulator now runs into that HDHomerun and I'm happily able to get TV in all the rooms again. The picture quality is high and doesn't seem to diminish at all through the two chained devices. I highly recommend this modulator if you live in an very rare situation like mine where the reception area is over powered or overlapping signals or whatever the problem was.

Excellent device! Happy I took the plunge!

So far, after two weeks, it seems to be a solid device. Picture quality is top-notch!

The documentation is far too sparse considering the many setup options. For example, there's a "Captions" port, but no information at all on how to utilize it. Most features are barely explained. But ... there's enough basic info to easily get up and running!

I cannot vouch for the network connectivity because I haven't tried it yet, but I'd imagine it should be fine.

It would be very helpful to be able to set program data in addition to just the channel numbers.

Overall, note that I'm pointing out some issues yet STILL rated five stars! You'll love the device ... do it!
