Connecting Cables Checking RF Cable Connection After connecting the RF cables, perform the continuity test and feeder cable return loss to check if the RF cable is changed and measure VSWR of antenna and RF cable. Connection Part of System External Interface Connector Antenna Measure all cables of section ~ . The measured VSWR should be the specification value or less. If the VSWR exceeds the specification value, disassemble the connector and measure each section separately. Checking VSWR for Minimum Cable Bend Radius and Length of RF Cable If the VSWR value for minimum cable bend radius and length of RF cable is not applied, system may not work properly because RF signals cannot transmit or receive smoothly. So, the VSWR value for minimum cable bend radius and length of RF cable must be checked and applied. Cautions When Measuring VSWR When measuring VSWR, if you open the antenna port when the transmission output is not completely off, a spike signal may flow into the reception path, which may cause damage to LNA. Make sure the transmission output is completely off when measuring VSWR. Checking the Specifications of Antenna/Arrestor Connector Depending on the supplier or manufacturer of antenna/arrestor the connector type may be different. Also, the detail specifications of a connector may be different depending on cable type even for the same connector type. Therefore, check the detail specifications of a connector before preparing parts. Ex) 3-78 Din Type-Male: for 1/2 in. Feeder line, for 7/8 in.

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. Connect the antenna not making the alien substance flowed so that Passive InterModulation Distortion (PMID) is not affected. 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. A-1 2600-00F1W8GAA Ver. 4.0 ANNEX A. Sector Antenna Installation A.3 Sector Antenna Installation The method of sector antenna installation is as follows. 1) Put up an antenna pole and insert the sector antenna into the antenna pole using a fixing clamp. 2) Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and bottom. 3) Adjust the tilted angle of the antenna by taking the signal strength into account. The bolts on the upper and lower guide clamps must be loose as to allow angle adjustment of the antenna. 4) After adjusting the antenna angle, tighten up the 4 loose bolts on the upper and lower guide clamps.

Installing Feeder Cable B.1 Cautions When Installing Feeder Cable When installing the feeder cable (GPS/RF cable), the following cautions shall be considered: Put a plate to work not to make damage for the surface of the feeder cable. If there is external damage of the feeder cable, cut the damaged part and work wiring. After connecting the antenna to the feeder cable, finish the connection part of the contracted pipe using the contracted tube. Attach the cognitive tapes to the both ends of the feeder cable, which makes it easy to recognize. When connecting cabinet, antenna and lightening arrestor, etc. to the feeder cable, connect strongly to prevent from generating reflected wave. The curvature radius should be maximized, keep the minimum curvature radius.
