Dear All,
I am confused about both types of tilts given to BTS Antenna in GSM networks.
Someone please clarify it.
Thank you.

mechanical tilt implies that an antenna is physically moved (tilted) while electrically tilting usually implies that a phase taper is introduced in the aperture to tilt or scan the beam.

Mechanical tilt:
Beam tilted by placement of the antenna with the help of mounting accessories.
Electrical tilt:
Beam tilted by varing the phase (using phase shifters)of the antenna elements.
