It's easy to think that an amplifier can somehow magically make a small antenna more powerful... The reality is that that is not true.
Antenna gain and amplifier gain are not the same thing. To use an analogy, think of an antenna as a well and an amplifier as a pump. A well that is not drilled deep enough would be analogous to an antenna that was too small, lacked the signal gathering ability to receive enough 'clean' signal. If you put a powerful pump at the bottom of that shallow well, you can only expect to get high pressure mud at the tap.
If you post a link, we will be happy to suggest an appropriate antenna for you.
