Installation Notes 7. If any part of the antenna system should come in contact with a power line, don't touch it or try to remove it yourself. Call your local power company. They will remove it safely. 8. If an accident should occur with the power lines call for qualified emergency help immediately. Installation Notes General Installation Instructions for Mast-Mounted Antennas The following instructions are common to most mast-mounted installations. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Assemble your new antenna on the ground at the installation site. Attach the antenna to the mast and connect its coaxial cable while you are on the ground. If you lose control of the mast while raising it, make sure that it does not fall in the wrong direction. Use a durable non-conductive rope secured at each 2-foot level as the mast is raised. Have an assistant tend the rope, ready to pull the mast clear of any hazards (such as power lines) if it begins to fall. Use the mounting bracket provided with the antenna. If the installation will use guy wires: a. Install guy anchor bolts. b. Estimate the length of guy wire and cut it before raising the mast. c. Attach guy wires to a mast using guy rings. Carefully connect the antenna and mast assembly to its mounting bracket and tighten the clamp bolts. a. For a guyed installation, you must have at least one assistant to hold the mast upright while you attach and tighten the guy wires to the anchor bolts. Attach the provided self-adhering DANGER label at eye level on the mast. Install ground rods to remove any static electricity buildup and connect a ground wire to the mast and ground rod. Use ground rods designed for that purpose, not a spare piece of pipe. Grounding the Antenna Follow these guidelines to ground the antenna in accordance with national electrical code instructions. 1. Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires for both mast and lead-in. Securely clamp the wire to the bottom of the mast. 2. Secure the lead-in wire to an antenna discharge unit and the mast ground wire to the building with stand-off insulators spaced from 4 ft (1.2 m) to 8 ft (2.4 m) apart. 3. Mount the antenna discharge unit as closely as possible to where the lead-in wire enters the building. 4. Drill a hole in the building's wall as closely as possible to the equipment to which you will connect the lead-in cable. Cisco Aironet 13.5-dBi Yagi Mast Mount Antenna (AIR-ANT1949) 4 78-14720-02
