3.3.4 Installation of the RBS antenna on the pole mounting

Considerations

– The antenna must be installed before the RBS unit.

– The form of the sectored antennas may vary. Always refer to the "TOP" marking on the antenna

when installing on the pole mounting.

Storage (Figure 27 – Installing the RBS unit antenna)

1. Position the RBS antenna against the pole mounting support (ref. 2), and install it at the opposite

side of the RBS unit.

2. Secure the RBS antenna using seven M6 x 25 screws (ref. 3) and onduflex washers.

Figure 26 – Antenna nose

WHATEVER THE TYPE OF ANTENNA, WHETHER FOR VERTICAL OR

HORIZONTAL POLARIZATION, ALWAYS POSITION THE ANTENNA WITH THE "TOP"

MARKING UPPERMOST. THE ORIENTATION OF THE ACCESS GUIDE

DOES NOT DEFINE THE POLARIZATION.

TAKE CARE NOT TO DAMAGE THE O-RING SEAL ON THE NOSE OF THE

ANTENNA CONNECTION: SEE Figure 26 – Antenna nose.

IF THE RBSs ARE NOT TO BE MOUNTED IMMEDIATELY AFTER THE

MOUNTING OF THE ANTENNA, PROTECT THE CONNECTION NOSE

(FROM WATER, DIRT AND IMPACT).

Stages 1. Remove the two transparent plastic protective caps : that of the antenna and that of the RBS unit. IMPORTANT: REMOVE THE CAP WITH CARE, TAKING CARE NOT TO DAMAGE THE SEAL WINDOW AT THE BOTTOM OF THE GUIDE.

slots in the "nose" of the antenna. Note: the RBS-DBS link cable (N point) should be towards the base of the transceiver. Note: the sectored antenna must be placed with the TOP marking uppermost, the antenna "nose" slots coinciding with those of the RBS. The waveguide needs to be positioned so that it is aligned with the antenna’s rectangular orifice. 3.

3.3.6 Antenna alignment REMINDER: THE RADIO UNIT/ANTENNA ASSEMBLY MUST ALWAYS BE MANIPULATED BY THE RADIO UNIT’S HANDLE ONLY. 3.3.6.1 Deflection characteristics The deflection obtained with the turnbuckles is : elevation = ± 25° and bearing = ± 10°. 3.3.6.2 Definitions about antenna alignment Tilt or Elevation : angle of tilt from the horizontal. Tilt UP : the antenna points upwards. Tilt 0 : the antenna is horizontal. Tilt DOWN : the antenna points downwards. 3.3.6.

3.3.6.4 Coarse azimutal alignment of the antenna The elevation alignment is performed only with the elevation turnbuckles. If the elevation angle is higher that (+ 5°) or lower than (- 5°), it is necessary to: – remove completely one of the 2 screws fixing the antenna support on the azimut support and, – insert it in the third hole accessible as shown in the Figure 31 – Elevation coarse alignement of antenna. If: -5° < α < 5° Put the screws in the two external holes.
