Amplifiers only help if you have some signal, but not enough. They can help make up for losses from long cable runs. If a channel will decode in a scan, but you can't get a watchable picture, an amplifier may help.
Sometimes noisy amplifiers can do more harm than good, especially with VHF. Amplified indoor antennas seldom receive praise for having great built-in amplifiers. Amplifiers can be detremental if a signal is already powerful without an amp. Indoor antennas seldom receive praise for their ability to receive VHF signals.
