This is where you want it.

I hope this is a good quality splitter you got there.

Good quality cable?

Good quality splitter? Nothing plastic, ugly little metallic boxes are
usually better.

Nope, this is not the place it would amplify the signal as well as any
noise inserted by the cable, splitters, connectors, etc...

If you can, this is the best place to do it.

Check your cables, the connectors (switch to well mounted F everywhere),
check for the status (rust and all) on the connections outside...

Minimize anything that could deteriorate the signal on its way to your
tuners.

When I moved into my current house, I changed all connectors, got rid of
ugly splitters, trashed a supermarket amp+splitter close to the TV and
replaced a few cables. I have gained 15% signal :o)

Next, I will replace the main antenna cable, change the antenna with one
with more elements and an amp at the mast, and make sure all
connectivity is protected from the beautiful scottish weather.

I should easily get a jump of 20% more signal, mostly by cleaning the
path.

If you stick to your antenna-mounted amp, you should be OK.
