No. The elevation angle of the first (or any) lobe is formed by the sum
of the main and the ground-reflected signals. If you tilt the antenna you
stop illuminating the two rays equally.

Is there any advantage to tilting a beam antenna up or down to match the
anetnna's elevation angle of maximum gain to the angle of the received
signal? It looks like the answer is yes but not enough to justify the
trouble/expense (unless you are tracking a satellite).
