3.5.2 Obstruction light
The obstruction light is mounted on the bracket (pos. 7) and the power cable is fixed with
cable ties to the rear side of the ladder or inside the cable trunking if space is available.
3.6 Antenna suport
3.6.1 Adjustment rails
As support for the antennas, the mast is equipped with rails for vertical adjustment, see Dwg.
No.: 16643A3
3.6.2 Mounting of supports
The vertical adjustment rails are mounted in the mast structure in accordance with drawing
dwg. 16643A3. The rails should be offset according to calculation made for the site in ques-
tion. They should be positioned horizontally such that the centre of the rail lines up with the
antenna offset given by the site data, and vertically so the centre lines up with the antenna
height. See example Dwg. No.: 16641A3/16642A3.
If the offset is too wide to be adjusted with the vertical rail, position the rail as far as possible to
the side and do the rest of the adjustment by sliding the antenna in the bracket pos. 2 dwg.
16792A3.
3.6.3 Antenna assembly
The antenna assembly, which comprises the radom and the antenna, is mounted to the verti-
cal adjustment rail. See dwg. 16792A3.
If NM antennas are supplied, see dwg. 10039A3.
From site data determine the exact distance between the antennas and to the ground. Adjust
the vertical antenna positions according to these data. Tolerance: +/-5 mm.
From site data determine the antenna offsets, i.e. the relative horizontal displacements
between the antennas. Adjust the offsets. Tolerance: +/-5 mm.
From site data determine the antenna forward shift i.e. relative vertical displacement. Adjust
the forward shift. Tolerance ± 2mm.
3.7 Cable trunks
3.7.1 Cable trunk brackets
All cable trunk brackets are prepared with 3 evenly spaced holes of 3.2 mm for cable trunk
fixes.
Brackets are mounted to the ladders in accordance with dwg. 16612A3.
Cable trunks are mounted to the brackets with rivets.
