RF Demodulators

At Markertek, we're proud to carry products that allow customers to modulate today's digital signals over RF TV channels. Whether you need to convert an HDMI camera signal for broadcasting, or you want to share a Powerpoint presentation across a school's television network, you can make it happen with RF modulators. We offer cutting-edge devices from brands like Thor Fiber, Blonder Tongue, and Pico Digital.

What Does RF Modulator Stand For?

Short for "radio frequency modulator", an RF modulator takes a radio frequency source signal and converts it so that it's compatible with another device. For example, you might have an RF modulator installed on your VCR or game console, so that an older TV can read the signal. Some devices have integrated RF modulators into their architecture as well. Meanwhile, in the broadcasting world, an RF modulator takes an A/V signal and converts it to a broadcast-ready RF signal. This is typically transmitted with aerial or coaxial cables.

First, Thor Fiber modulators like the H-HDMI-CC-RF provide an all-in-one solution for AV conversion and closed captioning. With the H-HDMI-CC-RF, you can take a camera, computer, or virtually any other device, and then create an RF channel to broadcast your video content on thousands of screens. Meanwhile, the Channel Vision E4200IR can create a user-selectable TV channel from any composite video signal, using a small four-channel device.
