Snow is actually electrical noise that is generated by the TV receiver and other electrical devices.
Another obstacle is the signal loss incurred while traveling through the transmission line connecting the antenna to the TV set. A pre-amp would be used to compensate for the losses in the transmission line as well as the noise level of the set. 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.
