Safety Precautions Safety Precautions Translated versions of the following safety warnings are provided in the Safety Warnings for Cisco Aironet Antennas, which is available at http://www.cisco.com. Warning Installation of this antenna near power lines is dangerous. For your safety, follow the installation directions. Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim was aware of the danger of electrocution but did

Installing the Antenna � Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away from these obstructions. � The density of the materials used in a building’s construction determines the number of walls the signal can pass through and still maintain adequate signal strength. Consider the following before choosing the l

Installing the Antenna � A drill � A #29 (0.136-in. (s.45 mm)) drill bit (for drywall installation, other surfaces may require a different size). � A pencil � A small mallet or hammer Mounting on a Vertical Surface Follow these steps to mount your antenna on a vertical surface. This procedure describes mounting the antenna on a drywall surface. If you are mounting the antenna on any other type of surface, your procedure may vary slightly. Step 1 Determine the location where you will mount

Installing the Antenna Suggested Cable Cisco recommends a high-quality, low-loss cable for use with the antenna. Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible, because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
