Tilts (of Antennas)
Antennas can have a tilt (up tilt or down tilt). Theoretically tilts with a maximum of ±90° are possible. Positive values describe up tilts, and negative values are used for down tilts. Practically tilts are most often negative (down tilts) and are in the region between 0 and –20°.

The sub-arms should be longer in case of a tilt – but in MASC this effect is not modeled as its influence on the accuracy is not visible in the output pattern.
