HD Antenna Digital Pre-Amplifiers

The function of a preamplifier is to amplify a low-level signal to the original strength of the signal. As an example if your signal loss caused by the length of your coax run or use of splitters is equal to 10db, you can add a 10db preamplifier to receive the original signal strength.

A preamplifier cannot make up for low to no signal at the original location. It can only make up for the signal lost over the coax.
