You may need both a distribution and low-noise amplifier, in which case, you’ll want to connect the preamplifier first – closest to your antenna - followed by the distribution amplifier. A distribution amplifier is typically what you’d look for when you have a cable television setup, and I’ve included some excellent distribution amplifiers in our selection of the best cable amplifiers – though, do look for a passive return amplifier, and not an active return one. On the other hand, a distribution amplifier amplifies everything equally – the signal as well as the noise. When shopping for a preamplifier, look for the words ‘low-noise’. – that typically accompany longer transmission distances, or come as a result of weather and other forms of interference. A layman’s way of saying this is that, it amplifies all the ‘good parts’ of the signal, while trying to reduce the ‘bad parts’ – the noise, distortion, fuzziness, etc. To quickly reiterate what the previous editors note has already expressed in some detail, A preamplifier is basically a low-noise amplifier, and it’s designed to amplify the signal while reducing the signal-to-noise ratio. However, I suspect that if you’re looking for an antenna amplifier, you are almost certainly going to be needing a preamplifier and not a distribution amplifier, so I’ve taken this opportunity to remove all distribution amplifiers from this list, and introduce some high-quality preamplifiers in their place.Ī Preamplifier vs. As stated by our previous editor, there are two types of amplifiers, and prior to my update, this list had a healthy mix of both distribution amplifiers and preamplifiers.
