| "VISION" 1, 2 or 4 way masthead amplifier with power supply. Similar to UXF4 but with ADJUSTABLE GAIN up to 20dB per output. Ideal if you are uncertain how much amplification you need. Very low internal noise (typically only 1.4 dB). Requires 5v to 12v. All connections use "F" connectors. The power supply connects to the down-feed from any of the UHF outputs. The power supply can be installed near any convenient mains power point. The arrows on the power supply indicate the route of the signal so the "in" arrow is the amplifier connection and the "out" arrow goes to a receiver/TV. Test with a short cable between PSU and amplifier to ensure that LED lights. Red LED indicates that power is reaching the amplifier. If LED does not light, please check all connections for continuity. Right click HERE to download data sheet. Click HERE to read about fitting 'F' plugs to cable. Click HERE for wiring diagrams. |
