Ver. CHAPTER 1. Before Installation 2600-00F46VGAA 2.0 Cable Path Inspection When installing a cable that connects between the rectifier, Main Ground Bar (MGB), and backhaul device, etc. within the system, the cable path length and the cable installation method, etc. must be inspected. Follow these guidelines when inspecting the cabling path.  A minimum cable length must be selected provided that it does not affect the cable installation and maintenance.  The cable must be placed in a location where it will not be damaged by external factors. (Power line, flooding, footpaths, etc.)  In areas where the cable can be damaged by external factors, ensure that measures are taken to prevent damages to the cable. (Cable tray, ducts, flexible pipe, etc.) Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable.  Cut the cable to the length determined in the Cable Path Inspection step.  Use a dedicated cable cutting tool.  Cut the cable at right angles.  Be careful to keep the cable away from any moisture, iron, lead, dust or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable.  Be careful not to damage the cable.  If the cable is damaged, cut out the damaged section before installing.  Run the cable so that it is not tangled. In particular, when installing a cable from a horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable.  Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with.  If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible pipe, and cable rack, etc. 1-8 © SAMSUNG Electronics Co., Ltd.

Ver. Smart MBS RRH-P4A Installation Manual 2600-00F46VGAA 2.0 ANNEX A. Sector Antenna Installation A.1 Cautions when Installing a Sector Antenna Precautions of antenna installation are as follows.  Sector antennas should be installed vertically. (±1°)  Antenna is the precise material, so be careful not to make damage or form change.  When moving antenna, use the tool suitable to rating. In addition, use the rated carrying device which is at least 200 % or more than antenna considering the stability.  Be careful not to give too much strength to the antenna.  If it rains, suspend connecting the feeder cable and antenna.  Fix it after adjusting the direction of antenna exactly.  Distance between steel tower and antenna and the distance between send-receive antennas are based on the antenna layout.  Attach the antenna on the position specified in the drawing.  Install the antenna not to make a feature change of the antenna considering the direction of the radiation  When connect the connector to the antenna, not making the alien substance flowed and is not under the influence of PIMD.  Measure VSWR of all antennas and the value should be within the regulated value. A.2 Sector Antenna Layout The method of sector antenna layout is as follows. 1) Use the transit to adjust the antenna installation direction exactly. 2) Fix the direction of the sector antenna, same as the angle settled when designing the cell after installing the steel tower. 3) Arrange the antennas of each sector to the sector directional angle at right angles by adjusting the distance between antenna and steel tower. In the event of the station whose the direction between sectors is not 120°, install it to make the steel tower and antenna direction different being careful of the tilt and azimuth. 4) For circular platform, separate the antenna interval at maximum. © SAMSUNG Electronics Co., Ltd.
