Task

The Triple Mounting Kit is intended for antennas with a pitch of 700mm

between hinge brackets. It will provide mechanical downtilt capability of

0°-20°, and azimuth swiveling of ±30°. The Bottom Fixed Bracket only

provides swiveling, while the Top Adjustable Bracket provides downtilt

and swiveling. The Brackets will arrive assembled but the hardware will

not be torqued.

DISCLAIMER:

The installation, maintenance, or removal of an antenna requires qualified, experienced personnel. You must refer to the appropriate local safety codes and ensure proper electrical and

electromagnetic compatibility before proceeding with the installation. All local codes shall take precedence over information in this document. Antenna systems should be inspected once a year by

qualified personnel to verify proper installation, maintenance, and condition of equipment. Communication Components Antennas Inc. disclaims any liability or responsibility for the results of improper

or unsafe installation. 50-000099-01 Installation Guide

Step

Task

Attach the Bottom Fixed Triple Mount Bracket by separating one Clamp

Bracket from the assembly, by removing some of the associated hardware

(see Fig. 3). Place the Bracket on the mast at the correct height in the

orientation shown, and also pointing in the desired direction as shown in Fig. 3.

Reinstall the Clamp Bracket and the associated hardware. Adjust the M12

threaded rods to balance the protrusion on either side, and tighten the M12

nuts to a torque of 54±2.5 N·m (40±2 ft-lbs.).

Step

Task

Attach the Top Adjustable Triple Mount Bracket by separating one Clamp

Bracket from the assembly, by removing some of the associated hardware

(see Fig. 4). Place the Bracket on the mast in the orientation shown, at a

height of 700mm above the Fixed Bracket (see Fig. 5) and also pointing in the

same direction as shown in Fig. 6. Reinstall the Clamp Bracket and associated

hardware. Adjust the M12 threaded rods to balance the protrusion on either

side, and tighten the M12 nuts to a torque of 54±2.5 N·m (40±2 ft-lbs.).

Step

Task

Install the 1st antenna/radio assembly on to both the Fixed Bracket using 2

pcs. each of the M10 hardware, and the Adjustable Bracket using 2 pcs.

each of the M10 hardware as shown in Fig. 7. Torque M10 hardware to

25±1.5 N·m (18.5±1.5 ft-lbs.). If further alignment is required loosen the M12

hardware holding the mast brackets in place and adjust the alignment of the

1st antenna/radio assembly in the direction specified by the site engineer.

The orientation of the Antenna is normal to the sector unless specifically

required otherwise.

Task

Once properly aligned torque M12 clamp hardware to 54±2.5 N·m

(40±2 ft-lbs.).

Completed installation with 0° MDT (Mechanical Downtilt) should appear

as shown in Fig. 8.

Step

Task

Perform Steps 8 thru 11 on one antenna/radio assembly at a time. At

the 0° MDT (Mechanical Downtilt) position, loosen all fasteners labeled

‘A’, on both sides of the brackets (Fig. 10). Repeat for individually for

the 2nd and 3rd antenna/radio assemblies.

Loosen two nuts labeled ‘B’, slide back the latch ‘C’, support the

antenna and remove the downtilt bolt ‘D’ (Fig. 10).

Step

Task

Allow the antenna to move such that the hole designated ‘8’ (8° MDT) lines

up with the mating hole immediately behind (Fig. 11).

Insert the downtilt bolt all the way, slide the latch up to engage with the

downtilt bolt (Fig. 11), and tighten the two nuts to a torque of 2.5±0.2 N·m

(2.0±0.2 ft-lbs.). Then tighten the fasteners loosened in step 8 to a torque of

25.0±1.5 N·m (18.5±1.5 ft-lbs.).

Step

Task

To adjust the azimuth direction, on one antenna/radio assembly at a

time, loosen the four screws labeled ‘E’. Simply rotate the antenna to

the desired position, and tighten the four screws to a torque of 25.0±1.5

N·m (18.5±1.5 ft-lbs.). This can be done at any MDT setting. Repeat as

necessary for the 2nd and 3rd antenna/radio assemblies
