Either, but you'll probably get better results if you put it at the beginning
of the run.

It should always be at the beginning, unless it is absolutely not possible.

Good quality cable may result in not even needing an amplifier, but here
it the reason why it may be needed and why it shouuld go at the beginning
of the run:

The longer the cable run, the weaker the signal will be coming out the
other end. If the strength of the signal coming out the other end is too
weak, or even borderline, boosting it is likely to bring it up to a useable
level to get a good picture.

That would suggest that boosting it at either end is fine, however one
must consider noise. The cable, even though shielded, will pick up some
noise along its length. Amplyfing the signal at the end of the run will
amplify the noise along with the signal. Amplyifing at the beginning will
boose the signal you want so that at the end it will be a useable level
while leaving the noise unboosted.
