Channel Master Model 7778 Titan2 MATV Mast Mounted Preamplifier with indoor power supply. The Titan range of mast mounted amplifiers has been completely reengineered and updated. These amplifiers represent the ultimate in preamplifier performance. They are designed for use as an ultra low noise, ultra high gain preamplifier for deepest fringe applications and MATV headend applications. Their very high signal handling also makes them suitable for use as a mast mounted, ultra low noise distribution amplifier for use in small MATV systems. All models feature 75 ohm, input and output connections in line with modern headend engineering practice.
