1 Installation Instructions 4 ft CompactLine Antennas (with E-Mount 200 km/h) SB, SBX NMT (e) These installation instructions have been written for qualified, skilled personnel. The antenna shall be inspected once per year by qualified personnel to verify proper installation, maintenance, and condition of equipment. It is important to adhere precisely to all parts of the installation instructions. RFS disclaim any responsibility resulting from improper or unsafe installation. RFS reserves the right to alter details at any time, especially with respect to technical improvements. These Installation Instructions are valid for antennas in the following version: - Ø 1.2 m (4 ft) - Single or Dual polarization - Pipe mount for installation on pipe Ø 114 mm - Antenna offset to the left or to the right - Standard installation on 114 mm pipe with offset to the left - Safety collar for an easier installation - 2 spindles for fine adjustment of Elevation of ± 15 and Azimuth 5 - with shroud, shroud aperture covered by a rigid radome km/h version : With sway bar Ø 27 mm x 1.35 m (mandatory) Sales department : Radio Frequency Systems Kabelkamp 20, D Hannover (Germany) Tel Fax Plant : RFS France Trignac (France) Tel +33 (0) Fax +33 (0) /11

If your are not concerned, skip this step, you can install it later. 5 - Assembly of the radome (Only if feed system not already installed) - Position the radome over the shroud (drain hole towards the bottom when the antenna is installed). - Fix the radome with 4 screws handtight every 90 around the circumference. - Fix the remaining screws and handtighten. - Tighten all screws. 15 screws M5x20 15 curved washers B5 15 washers Offset left Drain hole at the antenna bottom (toward the ground when antenna is installed) Drain hole at the antenna bottom (toward the ground when antenna is installed) Offset right NMT e 5/11

6 6 - Assembly of the mount (Feed system not shown, if already installed at chapter 4.) For easy operation of the bolted joints, and correct torque tightening, «Anti Seize» Installation Paste must be applied to all threads of bolts and fine adjustment spindles. After this, keep the lubricated threads free of dust and dirt! (a Torque Table is attached for specifications) Connecting Support Mount 6.3 Carefully turn up the antenna to have the radome face down 4 screws M8x25 4 SL washers A8 4 nuts M8 Offset left Offset right Spindle M10x100 2 brass nuts M10 2 washers SL screws M10x25 2 washers 10.5 Ø30 Steel U-Mount 4 ft NMT e 6/11

7 7 - Feed system installation (Refer to Feed Installation Instructions joined) 8 - Azimuth safety collar installation on pipe support Note that the installation of the antenna should be accomplished by qualified personnels, and well trained person in fair climatic conditions (In any case, always respect the safety regulation in effect in the country). Activities involving the use of pulleys, ropes, carabiners and others accessories to hoist antennas and associated products are inherently dangerous. You are responsible for your own actions and decisions. The use of hoisting systems must be done by qualified and skilled personnel. Always use certified and controlled equipments, and be sure to respect the breaking load and the working load limit of each element (pulleys, ropes, carabiners ). RFS disclaims any responsibility in case of non repect of these warnings..

After complete Azimuth fine adjustment, lock each first nut of the V-bolts (greased) at the specific torque, (refer to torque table joined) then tighten the second nut against the first one using usual wrench (do not use 2 wrenches to fix the second nut). Then tighten the 2 brass nuts M10 of the Azimuth spindle. NMT e 10/11

11 14 - Sway bar pre-assembly Fixing clamp sway bar (L-Profil 60x60) SL nut M10 Washer 10.5 Sway bar extremity Screw M10x30 2 U-bolts M6/27 4 washers nuts M6 Typical config. for direct mount on angle tower structure Washers 10.5 SL nuts M10 Screw M10x30 Alternative config. With optional interface SMA-SKO-UNIVERSAL For installation on tower pipe or angle structure Fixing clamp sway bar (L-Profil 60x60) SL nut M10 Washer 10.5 Screw M10x30 Optional interface SMA-SKO-UNIVERSAL Fixing plate sway bar 27 Screw M10x30 Washer 10.5 SL nut M Sway bar installation (Feed system not shown) For convenience the fixation of the sway bar on the tower structure must be done after complete fine Azimuth & Elevation antenna alignment. Installation on the antenna Sway bar orientation Antenna casting ring Sway bar clamp SL Nut M10 Washer 10.5 Screw M10x25 SL washer 10 Screw M10x25 After sway bar positioning torque tighten all bolted joints ±25 max 16 - Final Check When the installation of the antenna has been completed, it is necessary to make sure that the installation instructions have been followed in all aspects. It is especially important to check that all bolted joints have been greased and are torque tightly locked. NMT e 11/11
