1). Mechanical tilt:- in this you bend the antenna mechanically
The major lobe will become heart shaped in case of larger tilts. and lead to unwanted distribution of signal in uncontrollable manner.

2). Electrical tilt:- this is done with the help of phase shifters.
The phase of the feed(voltage) to the dipoles is changed further leading to change in the radiation pattern in a better manner.

Effects:-
Mechanical Tilt Causes:
Beam Peak to Tilt Below Horizon
Back Lobe to Tilt Above Horizon

Electrical Tilt Causes:
Beam peak to tilt below horizon
Back lobe to tilt below horizon
All the pattern tilts
