The micro-housing allows all output ports of the amplifier to be facing down to simplify coaxial cable wiring in NID enclosures or small spaces. Patented auto-seizing F-port features a Cam Activated Mechanism to provide full contact pressure (>2,000 grams) on the center conductor for maximum reliability. Provides clean amplification of weak signals to overcome the poor noise figure in TV-tuners and converters. Unique surge protection on all ports without the use of arc gaps which may cause high impulse noise during discharge. Self-resetting circuit protection provides safe protection against short-circuits to minimize maintenance costs.
