- Install the reflector equipped with its mount on woodenbeams (to not damage mount parts with the ground) andkeep bolt threads free of dust.

- The reflectors rim and the shroud panels must be clean and

dry.

- Dismount the hoisting eye of the reflector (installed at factory)

- For the antennas ordered with a 250 km/h WindKit, if the 6galvanized steel pipes have been pre-installed in factory atreflectors back, you need to remove the 6 M20 bolts (locatedat the reflectors rim), before shroud panels installation, andre-use it for the assembly of the reflector/shroud junction at13 holes in front of the galvanized steel pipes (instead ofthe M6x25 bolts provided with the antenna).

9. Feed Installation(for customized antennas, see specific Feed Install. Instructions joined)The feed is a precision component which should be handled with special care duringinstallation. For instance, always carry the feed, supporting casting plate side. Any damagemay degrade the antennas performance. Repair of feeds is not possible in the field.

10. Installation of the planar radome(for antennas with shroud)Take care to avoid kinking of planar radomes during installation. Kinking will destroy theradomes, which are non-repairable

11. Sway bar assembly(for an offset Right)

After sway bar pipe installation, beforeantenna hoisting on the tower, attach thesway bar in vertical position at the elevationspindle with a small rope, to avoid possibleshock.

For an easier sway bar orientation, keepthe U-bracket sway bar free in rotationwithout gap until sway bar final attachmentto the tower. At this time, all bolted jointswill be torque tighten.

- Unpack the radome and carefully strech it over the shroud aperture- For radomes with RFS logo, align it with the vertical axis of the antenna

- For radomes without RFS logo, the central air vent mosquito net aperture must be oriented towardsthe antenna top

- Attach J-bolt with springs and smooth radome down as the springs are attached, but do notdisplace the edge protector on the shroud rim.

- Align the length of the springs to approximately 135 mm at each J-bolt, this will provide properradome tension.

- Choose the optimal place on the tower, to fix the fine adjustmentazimuth spindle system (respect the 25 sway bar orientation)

- After sway bar positionning, do not torque tighten nuts until elevation& azimuth adjustment.

After azimuth adjustment, lock each first nut on the M14 U-bolts at the specifictorque value specified on the torque table joined (the U-bolt threads must have beengreased before torque tightening), then tighten the second nut against the first oneusing usual wrench (Do not use 2 wrenches to fix the second nut). Then torquetighten all the nuts and bolts of the Azimuth spindle.

When the installation of the antenna has been completed, it is necessary to makesure that the installation instructions have been followed in all aspects.It is especially important to check that all bolted joints are torque tightly

locked.

Check that is freein rotation &orientation in anydirection withoutgap betweenparts.
