Check for following after antenna and GPS feeder system installation: 1/2” Indoor Jumper Indoor jumper is properly connected to terminal on cabinet top. Indoor jumpers are tidy, in appropriate length and bound on cabling rack in order. Jumpers are laid in layers according to sectors. 11.
Chapter 8 - Hardware Installation Check Outer grounding copper busbar employs a special reliable path to an underground ground grid. The line width is more than 50 mm2. For a building without a tower, antenna feeder ground at top is connected with nearby lightning protection ground grid on the roof. Feeder grounding cable is led from top to bottom. Separation angle between feeder and grounding cable is no more than 15º. Feeder cabling has no crisscrossing.
ZXC10 CBTS O1 Hardware Installation Manual Antenna Antenna support and tower are properly installed. Antenna model is according to networking planning design. Actual hanging height of an antenna is according to network planning design. RF and GPS antennas are included in the protection area of a lightning arrester (area within 450 down tilt from lightning arrester). Azimuth of antenna is according to network planning. Azimuth error of directional antenna is no more than 50.
Chapter 8 - Hardware Installation Check Environment Check Ensure that: Outdoor engineering wastes are cleaned after the installation is over. Front and rear doors and cabinet sides are cleaned. Clean all fingerprint and other stains on cabinet surface. Indoor unused materials are put away. Material in equipment room is kept in order. Everything indoor is clean and tidy. Any engineering waste materials are disposed off. Leave no cable clips or sundries at the installation site.
