Mast should be in vertical position. It can be inspected by Leveller from two
orthogonal directions. In case there is deviation to vertical, then it can be
adjusted by the guy ropes.
6.3.3 Rotator Installation
Figure 6-8 Rotator Assembly on the Mast (Extracted from [26])
Rotator is fixed on the mast when the mast is lying on the hand rail following the
steps shown in Figure 6-8 above. Initially, 0 of the Azimuth motor should be set
to the North. This can be adjusted by rotating the 3” mast inside the Pivot Block
with compass before tightening.
6.3.4 Antenna Installation
Wimo’s X-Quads were assembled according to the instruction. The VHF and
UHF antenna will be mounted on the two ends of a 1.8m boom through the
rotator. As the weight of VHF antenna is 2.3Kg and UHF one is 1.6Kg, in order
to balance the boom relative to the rotator, VHF has to be 0.74m to the centre
of the rotator.
Two antennas are designed to be foremast mounted on the boom by the
clamps. Before tightening clamps, antennas’ direction must be perpendicular to
the mast, which means the initial elevation angle is 0 once the mast stood up.
