Take care during transportation and installation, otherwise you will loose the good electrical performance of the cable Do nothing which can deform the cable handle with care during transportation note correct stocking of cable and accessories do not over tight the clamps do not bend the cable to much Make sure that the cable are clean always Do not leave metallic particle, humidity dust or dirt inside the cable Seal the cable ends or connector heads Note the installation instructions always Install all accessories e.g. connectors, grounding kits etc. in according to the installation instructions Cable handling Conserve the characteristics of the cable If the cable is deformed (e.g. by wrong bending), damaged or particles are left inside the performance will be lost (flow rate) Left particle Damaged 37 Side 14 of 41

15 38 Cable handling Shipping of the cable Drums packed on pallets protected by wooden lagging Short lengths of cable are shipped in crates or cartons Drums packed on pallets with only reduced protection Handle drums or cable rings with care! Seal the cable ends always Cable handling Transportation of the drum If a crane is used a special hanger is necessary to avoid damage of the drum flanges If fork lifts are used, the forks must be long enough to engage both flanges of the drum to avoid cable damage! 39 The drum has to be secured carefully during transport! Effect of careless handling Cable handling Transport of the drum on site Do not lay the drum on its side! Reels must be transported and handled in its up right position only! We recommend to use a cable drum trailer. 40 Side 15 of 41

16 Cable handling Transport of the drum on site After carefully unlagging secure the drum. Turning direction Do not remove the wooden planks before the drum is in position Note the safety aspects! Cable handling How to handle cable rings Lift up and turned the cable ring Protection by pipe rollers, wooden blanks etc. Wrong way! The cable ring has to be turned (like a drum) when pulling the cable, otherwise the cable will be twisted. If the twisted cable will be straightened afterwards the cable will be damaged in the twisted area Pull the cable step by step carefully look always to the man which handles the ring in order to see how many cable is available Or: Roll out the cable ring along the ground of the cable line/route and lift the cable in the final position later Cable handling Cut the cable Keep the cutting area down, in order to avoid dirt or copper shavings falling into the cable! 43 For provisionally cutting we recommend to use a cable trim to cut the cable. It produces nearly no copper chips during cutting. Side 16 of 41

17 Cable handling Cut the cable Cutting during hoisting/laying Not for installation of the connectors Cut with cable trim: - cable will be deformed, but nearly no copper chips will be produced during cutting. Deformed cables can be closed with hot shrink caps without problems. Cut with saw: - a lot of dirt from the jacket and copper chips will be placed on the dielectric. Make sure that all particles will be removed. 44 Before start the installation of the connector the cable has to be cut off again! Cable handling Clean the cable after cutting in depht Deburr inner conductor Remove all edges Even outer conductor Knocking - from the button side Clean 45 Remove all particles & dirt Metallic particle Do not leave any dirt & particles inside the cable, clean specially the dielectric very well 46 Cable handling Sealing of cable ends Seal the ends of the cable! We recommend to use heat shrink caps for sealing. Rough up the cable jacket with emery cloth (280 grain). Remove emery remnants with clean cloth and clean this area of shrinking with cable cleaner. Shrink the sleeve with a soft yellow flame by evenly applying a constant flame with a circular motion, beginning at the closed end. Side 17 of 41

18 Cable handling Bending of the cable RFS cables easy to bend, but not on this way! 47 Cable handling Bending of the cable Pull carefully bit by bit While pressing slide your hand 48 Note the minimum bending radius! r Do not press in the middle of the bow only, go along the complete bow with the same pressure Cable handling Devices for hoisting the cable Hoisting grips Pipe rollers Cable angle roller 49 Cable drum hydraulic jacks Cable drum trailer Side 18 of 41

19 Cable hoisting Hoisting grip types Hoisting grip closed type This hoisting grip are to be used only for cables without mounted connectors. Hoisting grip open type This can be used as well for cables with mounted connectors. 50 Cable hoisting Installation of hoisting grip open type 1. Place the hoisting around the cable, whereby the end with the connector shall be long enough to make the connection to the antenna without opening the hoisting grip. Both ends with the two enclosed flexible wire strands are to be 3 inserted in the two topmost net loops and then crosswise in the lower net loops and so up to the end (shoe close style) The meshes of the crossed wire strands shall not be smaller than the existing meshes of the hoisting grip 2. The two strand ends are to be knotted or clamped and to be secured in the net loops. The end of the hoisting grip can be fixed with tape Protect the cable area were the hoisting grip will be fixed to the rope for example with the safety cloth, wool etc. 4. Clamp the hoisting grip with clamps to the hoisting grip or hang in a hook Note: The maximum hoisting length per hoisting grip is 70m! Side 19 of 41

20 Cable hoisting Hoisting procedure 1. Protect the connector end from objects impending its way. 2. If the distance to the connector (worker 1) is too long, he will protect the hoisting grip from objects blocking its way. 3. If add. hoisting grips are necessary they have to protect also. 4. Observe and maintain - decelerate the drum turn. 5. Important Person! Observe this place - pull the cable and bend this bow manually. Connector with safety cloth or wool Hoisting grip The cable is slack above this hoisting grip The rope is tensioned! Fixed by tape Protect the fixing area with safety cloth or wool! Additional hoisting grip Do not remove the hoisting grips before all clamps are closed! Cable laying Horizontal runs If the cable will be pulled on the ground, we recommend to use pipe rollers to avoid any damaged of cable jacket. Horizontal runs must be protected against the weight of accumulated ice and damage through falling ice or other objects. 53 Even if it is necessary to drag the cable over sharp edges of buildings and tower members, protective measures must be taken (e.g. with wooden planks or observed by an installer). Side 20 of 41

21 Cable laying Pulling in horizontal hollow tubes The diameter of the hollow tube (or underground cable duct) shall be at least twice the CELLFLEX cable diameter (e.g. min. 100mm for LCF 78-50). The bending radii for tubes installation shall be at least twice the minimum bending radius (for multiple bending) of the respective LCF cable (see data sheet). Inter- connections of several tubes must not damage the cable during pulling/pushing the cable. - Avoid any risk of blocking. Avoid sharp edges during pulling the LCF cable. Pulling of LCF cable can be supported by an additional layer of grease on the cable jacket. If the cable will be pulled with a winch, we recommend to use a measuring device to make sure the max. tensile force (see data sheet) will not be exceeded. 54 Connector installation Tools for installation Preparation tools for easy and safe installation of connectors Complete tool case for CELLFLEX cables are available 55 Connector installation Tools for installation Poly Hook Spanner Type 60-90/5 Art.No for LCF & Type /6 Art.No for LCF Note: twice are needed always Included in tool box Not included in tool box Saw blades straight line with smooth saw tooth Art.

40 Installation examples Outside buildings C-rails fixed to adjusted flat iron C-rails fixed to the wall 111 Installation examples On towers 112 With LCF cable to the TMA Installation examples Bad installation example 113 Nearly nothing is well done! Feeder cables not correctly fixed (must be fixed on the end as well, Jumper cable has to fixed also) Jumper cable is bended to strong and to close to the connector (by doing so the cable will be damaged in a short time when moving due to wind) Cables laying in front of the antenna (that will influence the signal characteristic of the antenna). Grounding kits installed in a bended cable run (cable damaging and humidity) Grounding cables not in direct shortest direction to the ground (in case of lightning the voltage will damage some things) The grounding connection to the tower is corrosive because of the connection cooper to galvanized steel Side 40 of 41
