(09/02/08) 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.
