The Vision Plus VP2 Digital Amplifier is fully wideband for television transmissions and is designed to be used with Vision Plus STATUS antennas with orange logos that do not have pullout telescopics. The VP2 can also be used with the following range of antennas that only provide a TV output: IMAGE 410, IMAGE 420 IMAGE 440, IMAGE 610 and IMAGE 620. This powerful amplifier with high gain and low noise capabilities will ensure improved performance, especially in those areas that suffer with poor reception.
