A loop antenna is more or less flat until the stray capacitance of
the loop windings take it down.

I put a low-pass filter which cuts around 300-500 kHz on this one,
because I have a MW transmitter at 1062 kHz only 30 km from my house.

And that is the other good reason to use a loop: you can null out one
strong signal with the orientation.
