Trying to hook up a new DVD player, game console, or camcorder to a TV that only has an antenna jack? Terk's Mini Modulator is what you need. This compact, affordable modulator accepts the audio/video signal from your source component and converts it to RF for use with older TV sets. Hook up your cable TV or off-air antenna feed via the provided coaxial RF input; then, to select your connected A/V component, just turn it on auto source switching does the rest.
