Unfortunately, these devices weaken the signal, necessitating the use of an amplifier. Usually, there are two primary reasons you might need an amplifier for a TV antenna.įirst is if you’re using a splitter, which is usually the case especially when using distributor amplifiers, as we’ll see below. Do You Need an Amplifier for a TV Antenna? The amplifier increases the signal’s gain (ability to increase the power of a signal) by concentrating the signal to one small area that the TV receiver can detect. What it does is it balances the noise and signal (S/N) levels before the signal reaches the TV’s receiver.īy doing that, the antenna amplifier creates a signal that’s receptive to the TV. That way, the signal is better and you can enjoy a better viewing experience.
