Universal RF Modulator Lets You Connect a Digital STB to a TV Without Composite Video Inputs

Universal RF Modulator

Many of us have old Analogue TV’s that are in tip-top shape and have a superb picture. They kept us entertained when we grew up and are now like a member of the family, so we can’t imagine parting with them.

Some of our beloved TVs can receive Digital TV with the aid of a Set Top Box (STB). You simply connect the TV antenna to the back of the STB, and then you connect the set top box to your TV using the composite video and audio inputs.

Unfortunately, some of our old TVs don’t have composite video inputs, which would usually prevent us from connecting a Digital Set Top box (STB) or DVD player. An RF modulator lets you take the composite video and audio output from your STB and convert it into a broadcast signal that can be tuned in on your analogue TV like a normal TV station.
