Amplified Indoor Antenna:The TV5 features a fully adjustable, low-noise amplifier, that is designed to optimize signal strength for any location. TERK"s patented amplifier bypass allows stronger local stations to bypass the amplifier entirely, preventing over-modulation and ensuring successful reception of the maximum number of available channels. Built-In Video Selector Switch:The TV5 offers the added convenience of a built-in video selector switch, creating a one cable solution for a video game, DVD player, VCR or other video component. With just a push of a button, you can now switch between TV and another video source without having to disconnect and reconnect any wires.
