A Pre-Amplifier (pre-amp) is a mast or antenna mounted amplifier used primarily to eliminate "snow" on the TV screen. Snow is actually electrical noise that is generated by the TV receiver and other electrical devices. The objective of any antenna installation is to deliver enough signal to the TV set to override the noise (snow). A "weak" signal is one that is not strong enough to override the level of the noise in the set. Another obstacle is the signal loss incurred while traveling through the transmission line connecting the antenna to the TV set. An antenna that has acceptable gain at the antenna tapoffs but encounters excessive loss due to long cable runs will also deliver a "snowy" picture to the TV set due to not enough signal makes it to the set to override the noise level. A pre-amp would be used to compensate for the losses in the transmission line as well as the noise level of the set.
TITAN 2
TMMATV Mast Mounted PreamplifiersThe 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.

The power supply that comes with this amp goes inside the building, so you do not have to run a separate cable for power. The unit inside the building injects voltage up the coax cable, so there is no need to put a power supply outside. Be sure not to place any devices in-line between the pre-amp and power supply, or the voltage will be blocked and the unit will not function correctly.
