3)
Make sure that the installation direction of the antenna support would not influence
the receiving (RX)/transmitting (TX) performance and direction adjusting of the
antenna.
4)
If necessary, take suspension measures to avoid distortion of the antenna support
as it will be in use for a long time.
5)
Whirling arm should be reinforced by reinforcing arm. The length of expansion arm
and whirling arm may be determined according to the onsite situation. The fracture
should be soldered with cover plate to avoid leaking water.
6)
All the soldered parts should be secure enough without dry joint and open solder
point. The surface of the support should be covered by anti-rust silvery paint.
Better choose zinc-coated steel for the support.
III. Installation procedure
1)
Install a fast pulley on the tower top. Use one or two lifting ropes to hoist the
support to the tower platform via the fixed pulley. Besides, a rope is needed to
control the upward direction of the support;
2)
Determine the installation position of the antenna support on building-top
according to the antenna and feeder installation diagram in the engineering design
drawing.
3)
Fix the support on the tower with a U-shape fixing clip, as shown in Figure 3-14.
4)
Connect the tower platform guardrail and joint soleplate with M12
%
45 bolt.
