Long view, it looks like it's level at the attachment point on the mast. Could be the way the mast is seated cranked down in the tower also.

Ordinarily, the antenna boom should be level, but at some locations reception is improved by tilting the front end up and even less often tilting the front end down.
Tilting the front end up sometimes helps if there is a hill in front of the antenna in the signal path close to your location.
Tilting the front end down is used when the ground in front of the antenna slopes down away from you. The antenna is mounted close to the earth and the antenna picks up the signal reflected from the slope.
Both the 30-2476 and the HDB91X have a tilt adjustment.
