Distributed antenna system cabling is supported by J-hooks suspended from the structure above, with cabling routed back to the DAS equipment. The distributed antenna system cabling must remain outside of cable trays, though J-hooks may be attached to the side of a cable tray. When a distributed antenna system antenna is located in a hard lid ceiling, a junction box is provided at the ceiling for mounting the antenna with a minimum 1-1/4 inch conduit routed to an accessible location or back to the equipment. Long sweep bends are required with no more than one bend per accessible pull point. A bonding bushing is installed at the end of the conduit.
