                      RF Modulators

                      At Markertek, we're proud to offer quality RF modulators at affordable prices. If you're looking to view or distribute video content over a specific TV channel, you'll need an RF modulator. RF Modulators have been used at the home level to adapt DVD and VCRs to TVs with RF coaxial connectors. At the broadcast level, Cable TV providers and head ends on a college campus or at a hotel use them to push content on specific TV channels via broadband RF systems.

                      What is an RF Modulator?

                      Essentially, you can use RF modulators to convert a baseband audio/video signal to an RF (radio frequency) signal. Originally, radios and TVs were designed to receive signals off-air (off of the airwaves) via an antenna, which were then demodulated by the device.

                      Today's video equipment can receive a direct signal via coaxial, HDMI, RCA and various other inputs. To connect equipment via the RF coaxial television input, you'll need an RF modulator to convert the signal.

                      This concept holds true for live broadcasting as well, albeit on a larger scale. Depending on your needs, it's possible to use RF modulators for CCTV camera feeds, live television, and other broadcasting applications.

                      Modulators from brands like Blonder Tongue, Pico Digital, Thor Fiber and ZeeVee can convert virtually any video source to an RF signal. These all-in-one units can even output HD-quality video as a radio frequency, and then encode the signal in H.264 or MPEG-2 formats. Whether you need to distribute HD, a DVD player or digital signage source, our robust modulators are built to support multiple sources at once.

                      To learn more about our modulator selection, call us toll-free at 800-522-2025 or chat with us live. If you need an RF modulator for your broadcasting system, we offer free shipping on all orders.
