2. All mobile networks worldwide face tower-top weight & wind-load problems because:
1. Need to place RRUs as close as possible to the antenna system
2. Need to replace the existing antennas with other larger in volume & weight
3. Need to install more and more antennas tower-top today and in the future
Taking into account that the antenna masts are designed and implemented on the basis of
“earlier” static data, it is currently being attempted to "light up" tower-top’s, so that they can
accommodate more, larger and heavier radio network material.

3. • It is known that on any antenna installation
on a mast, the “antenna-support" system (as
shown in left figure) is required to install the
antennas so as to allow the riggers during
antenna installation to align the antennas on
the desired azimuth direction.
• Removing the “antenna-support" system
one can alleviate the unnecessary weight
and wind load at tower-top, BUT the riggers
will not be able to align the antennas
towards the desired azimuth direction, as
this is instructed by the radio teams…

5. With the deployment of the proposed
azimuth steering kit, the antenna alignment
towards the desired azimuth direction can
be easily performed without the need of the
legacy “antenna-support" system.

6. …for even 8 antenna systems side by side…
Please note that for different antenna types, 3 pieces of C1A1T0.18 azimuth steering
kits are required (common top clamp, different bottom clamp).

7. …for any azimuth direction requested…
+45° -45°Please note that the applicable azimuth range per antenna is ±60° (of 5° step). Full
deployment of the 120° azimuth range depends on antenna’s width, where under this
configuration minimum is assumed + or - 60°, w.r.t. the mast side direction.
(total azimuth range per antenna set 180°)

8. …and with absolute heading accuracy!!!
Please note that for known mast side directions w.r.t. North, alignment tools are not required for
antenna alignment. The antenna’s azimuth direction accuracy fully depends on the mast’s side
direction accuracy (as installed and delivered). The azimuth kit 5° step offset precision is <0,005°.
(@0° offset, the antenna heading is the same
to the mast’s side heading w.r.t. North)
