Installation Notes Caution There may be wires in the wall. Make sure your drilling location is clear of any any obstructions or other hazards. 5. Pull the cable through the hole and form a drip loop close to where it enters the building. 6. Thoroughly waterproof the lead-in area. 7. Install a lightning arrestor. 8. Connect the lead-in cable to the equipment. Choosing a Mounting Location The antenna is designed to create a directional broadcast pattern. To achieve this pattern, the antenna should be mounted clear of any obstructions to the sides of the radiating element. If the mounting location is on the side of a building or tower, the antenna pattern is degraded on the building or tower side. Site Selection Before attempting to install your antenna, determine where you can best place the antenna for safety and performance. Follow these steps to determine a safe distance from wires, power lines, and trees. Step 1 Step 2 Measure the height of your antenna. Add this length to the length of your tower or mast and then double this total for the minimum recommended safe distance. Caution If you are unable to maintain this safe distance, stop and get professional help. Generally, the higher an antenna is above the ground, the better it performs. Good practice is to install your antenna about 5 to 10 ft (1.5 to 3 m) above the roof line and away from all power lines and obstructions. If possible, find a mounting place directly above your wireless device so that the lead-in cable can be as direct as possible. Tools and Equipment Required A mast mounting installation kit is shipped with the antenna. To install the antenna on a mast, you need the following tools and equipment. • A 7/16-in. (11.1 mm) wrench • Cable ties or electrical tape • Coaxial cable weatherproofing material (such as CoaxSeal) 78-14720-02 Cisco Aironet 13.5-dBi Yagi Mast Mount Antenna (AIR-ANT1949) 5
