The beam downtilt is factory set.

The beam downtilt below the horizon is adjusted by rotating the hex

socket located at the bottom of the antenna - Figure 5). Turning the hex

socket in a clockwise direction increases the beam downtilt below the

horizon. Turning the hex socket in an anti-clockwise direction decreases

the beam downtilt below the horizon. Beam downtilt setting in degrees

below boresight can be read off the scale at the base of the antenna.

The downtilt setting is read from the face of the antenna bottom end cap

at the point where the scale protrudes.

AISG Compliant antennas are compatible with AISG compliant control

unit equipment. For operation of downtilt using AISG compliant

controllers see the controller documentation. Where manual override of

RET control is provided at the antenna bottom end cap, operation is

identical to that described above for MET antennas.

WARNING: During downtilt adjustment ensure the hex socket is not

turned past the minimum and maximum positions as shown on the

downtilt indicator scale. Forcing the hex adjustment beyond this point

may lead to damage of the downtilt mechanism. Using power drills

and electric screwdrivers to adjust downtilt may also lead to

damage of the downtilt mechanism.
