Question 1

Should you install a preamplifier if you live near a TV transmitter?

Accepted Answer

If you live near a TV transmitter, then there's no need to get a preamplifier. On the contrary, having one can cause problems because then the signals will be too high.

Question 2

How can you determine if you need a preamplifier?

Accepted Answer

One way to accurately measure if you need a preamplifier is to get the signal levels checked using a field-strength meter. But that's not a plausible option for home installations. The alternative is to use the Antenna-Selection tool and then put your address in it. This will show you all the available channels in your area. If the station is grey or red, then having an amplifier will boost the signal strength.

Question 3

Should you use 2 preamplifiers on your TV antenna?

Accepted Answer

First of all, know that the antenna amplifier sends a low-level signal to the TV through the coaxial-cable. You can opt to connect a preamplifier with the coaxial-cable splitter or on the very main antenna as well. If you use an amplifier on both these locations, then the signal will get doubly boosted. If your connection is so poor that one amplifier isn't getting the job done only then add-in another one. Otherwise, there's no need to get another one and get higher signals than what's needed.

Question 4

Will an amplifier guarantee new channels?

Accepted Answer

There are no guarantees that you will give more TV channels just because the signal is now amplified. This is because various other factors come into play like the building materials, the antenna being used, the location of the TV transmitter, and more.
