Difference Between a Distribution Amplifiers and a Preamplifier

What is the difference between your PA18 and CPA19 preamplifiers and what is the difference between a distribution amplifier and a preamplifier? Thanks! From Paul in Union, MO

Hi Paul,

A distribution amplifier is helpful if you have a good signal at the splitter, but not after splitting. Distribution amplifiers are usually one piece and are meant to be used indoors. They are used to overcome splitter loss and meant to “distribute” TV signals to multiple locations.

A digital antenna preamplifier can be used outside with your outside antenna. It usually comes as a 2 part unit with the amplifier mounted at the antenna and the power supply mounted in the house. A preamp is meant to overcome signal loss due to long cable lengths between the antenna and your TV or splitter.

The CPA19 has a slightly lower noise figure than the PA18 and was designed specifically to compliment the Clearstream line of antennas.

Do I Need an Antenna Amplifier with my Antenna?

Looking about getting the DB4 UHF HDTV Antenna. All stations are located with 35 miles of our location. Will this antenna require any amplifier? We will be placing the antenna in the attic area, no metal roof. Coax will be no more than 20 feet in length running to a single TV. From William in Odessa, Missouri

Hi William,

We always recommend trying to put antennas outside on your roof instead of your attic. Even though you don’t have a metal roof, your home insulation and other side wall materials in your home have a greater chance of getting in the way of broadcast signals in the attic. If those materials are wood, vinyl or something else you could experience a 20% or more loss in your signal.

With that said however, we have had customers use the DB4 in their attic with mounts and without mounts and report that it works great. It will really depend on your specific location, house structure and terrain. Find out more about your location at www.antennapoint.com.

You shouldn’t need an amplifier with a 20 foot coaxial cable. However, sometimes an amplifier is necessary to overcome signal loss related to splitters and junctions. I would not recommend adding an amplifier if you don’t need one. An amplifier does not create a signal, and may increase noise. However, if you are using a splitter for several televisions in your house, you may need an amplifier.
