... that you must start with a clean, possibly weak, signal. If there is NOT a clean signal to start with, then all an amp will do is amplify the noise along with the signal. Then, you will have a dirty, strong signal which is really no improvement. In most stores where they have many sets running, they NEED to amplify the signal.

Rooftop antennas (usually) provide adequete signal for 2 to 4 sets if properly split, all cables are good, connectors properly installed, and unused splitter outputs are terminated.

You would be surprised how many problems are caused by loose F connectors. They may look good but may not be crimped correctly. I have noticed that, in many cases where 3 (out of 4 ) sets are working fine but the fourth isn't, there's a good possibility there's a problem with the cable or the connectors.

Generally, if you have to use an amp, it should be installed as close to the antenna itself.
