Installation Instructions
UDS Antenna´s Family With 120 cm Diameter
DESCRIPTION
The UDX antenna´s family are the Ultra High Performance antennas, operating in single polarization,
provided by Brasilsat Harald S/A. The antennas are designed for short-haul microwave systems in all
common frequency ranges from 7 GHz to 23 GHz. They are typically deployed in dense urban areas,
metropolitan and suburban locations, aggregation points. They are especially optimized to integrated
radios to reduce costs, installation complexity and time.
This Installation Instruction is valid for antennas in the following version:
• Antenna models: UDS71-12S; UDS107-12S; UDS144-12S; UDS177-12S and UDS212-12S
• Reflector Ø 120 cm;
• Dual polarization;
• Standard mount for support pipe Ø 114 mm;
• Reflector aperture covered by a radome;
• The design allows a fine adjustment range of +-10° for elevation and +-15° for azimuth;
NOTE
� This instruction must be read completely before sta rting the installation. � The installation/maintenance/removal need to be mad e by qualified personnel. � Brasilsat Harald S/A disclaims any responsibility f or the result of improper and unsafe
installation. � The pole/tower/other structural element involved to support the complete antenna as
described in this instruction must be verified/appr oved by structural specialist in respect to all the national/local regulation.
� All the required tools/instruments must be availabl e. � It is important to mount the antennas exactly as de scribed in this document. Don’t use
any parts, screws/nuts, not included in the packagi ng or not recommended by the supplier.
� The Antenna system should be inspected once a year by qualified and experienced personnel to verify proper installation/maintenance /condition of equipments.

2.2 Installation Steps
2.2.1 Install Shroud
There are red marks (“B”, “L”, “R”, “TOP” ) on shrouds. Also there are red marks (“B”, “L”, “R”, “TOP” ) on the reflector. Install the shroud B into the position B of the reflector, and then load bolt
M5*16 2 flat washers, a spring washer and nut. Install the other shrouds in turn of “L”, “R”, “TOP”. Don’t fasten all the nuts and bolts now. You can get more details about the installation in the figure 1-3
below.

Attention: When nuts, Flat washers, Spring washers, and anythi ng else drop into the
reflector during the installation, you must take th em out before installing the radome.

Figure 6: Installing Mounting assembly
2.2.5 Install Anti-slip assembly
First roughly decide the direction of the antenna. Install the Anti-slip assembly onto the proper height
of the mounting pole. The channel steel direction should be 45° between the antenna directions as
shown in figure 7. Fasten all the nuts in the end.

2.2.6 Lift the antenna to a tower
Lift the antenna to a tower with a rope through the lifting hole as shown in figure 8. In order to avoid the
antenna rotation, you need to tow the antenna with another rope as shown in figure 8.
`
`
Figure 8: Lift the antenna
Attention: To avoid falling and damage, please mak e sure the rope is tighten before lifting.
During the installation, please protect the antenna from hitting of other objects due to the wave of the antenna resulting from the wind or other cau ses.
2.2.7 Install the antenna to the mounting pole
Lift the antenna on the Anti-slip assembly of the mounting pole. Diameter ranges of pole for this
Mounting assembly: Φ115 mm. Install the antenna to the mounting pole with 2 U-bolts, 8 nuts (M14), 4
Flat washers. Mounting assembly must be clung to the Anti-slip assembly. Moreover, the channel steel
direction should be 45° between the antenna directi on as shown in figure 9. Don’t fasten all the nuts
now.

2.2.10 Adjust antenna elevation
Loose the nuts, bolts as shown in the figure below. After the installation, fasten them. Then loose the
nuts as shown in figure 13 to adjust antenna elevation. The range is ±10°, as shown in figure 13-14.
Adjust azimuth and elevation repeatedly until get the antenna to the proper position. Fasten mounting
assembly, U-bolt, bolts of Anti-slip assembly, articulated bolt assembly and all the other bolts and nuts.
