A better aerial might work still pointing thru the tree.

Only if the problem isn't severe.

That's what I meant. I should have said that less cryptically
given that you and Brian have commented on it.

Tree screening is very uneven and often moving the aerial up down
or sideways half a yard will make a tremendous improvement.

And if the current aerial is very poor, a decent one might be adequate.
