Fig.22 – ALFOplus with Standard mounting flange
Install the antenna using the antenna installation guide (specific for each antenna) inside the antenna box
provided by antenna producer. Keep attention to the position of the antenna feeder depending on request-
ed setting.
After the antenna is installed onto the pole, the ODU must be installed:
• position the three holes circular flange (1) on the antenna flange and align the three holes on the
circular flange with the three relevant holes on the antenna flange as in Fig.23
.
• insert and tighten the three 3mm M4 Allen screws (2) using a 3mm Allen wrench (torque = 2 Nm)
• add lubricant paste, e.g. MOLYKOTE P-40, on threads of four 25mm M10 bolts (3). The sliding sur-
faces should be cleaned. The paste should then be applied with a suitable brush, rag or grease gun.
It should not be mixed with grease or oils. Chemical protective gloves should be worn where re-
peated or prolonged contact can occur. Screw partially the three M10 bolts (3) on the antenna back
plate: each bolt should be tightened to have the square head out of the hole of about 13-14mm
(the thickness of hook (4), use 15mm spanner). The last bolt will be inserted in the closed slot.
• apply seal and lubricant grease Dow Corning 4 to the O-ring, protecting fingers with gloves, and
insert in the proper track on the ODU flange
• position the ODU vertically near the three bolts on the antenna flange and align the ODU to match
the antenna feeder.
• after the right position has been found, rotate 30° counter clockwise the ODU and approach the
ODU to the antenna flange in order to have the slots of the Standard Lock cross between the bolts
• rotate 30° clockwise the ODU to hook each slots on the relevant bolt
• when each slot is firmly hooked on the relevant bolt, tighten each bolt (use 15mm spanner,
torque=46mm)
• now insert the last bolt in the closed bolt (the upper) and tighten it.
