1. Consider the following before choosing the location for your antenna Signals penetrate paper and vinyl walls with little change to signal strength Signals penetrate only one or two solid and pre cast concrete walls without degrading signal strength Signals penetrate three or four concrete and wood block walls without degrading signal strength Signals penetrate five or six walls constructed of drywall or wood without degrading signal strength Signals will likely reflect off a thick metal wall and may not penetrate it at all Signals will likely reflect off a chain link fence or wire mesh spaced between and 1 1 2 in 2 5 and 3 8 cm The fence acts as a harmonic reflector that blocks the signal Install the antenna away from microwave ovens and 2 GHz cordless phones These products can cause signal interference because they operate in the same frequency range as the device to which your antenna is connected Choosing a Mounting Location The antenna should be mounted clear of any obstructions to the sides of the radiating elements Generally the higher an antenna is above the floor the better it performs If possible find a mounting place directly above your wireless device to ensure the lead in cable can be as short as possible Installing the Antenna You can install the antenna on any flat vertical surface on a pole or on a ceiling All hardware for mounting the antenna on a wall or ceiling is pr2. 5 Figure 5 Antenna Bracket Attached to Mounting Bracket SPHERKAL WASHER SCREEN MESH WASHER 254348 WALL BRACKET Step3 Determine the mounting location for the antenna Step4 Attach the wall bracket to the wall using the two screws provided Figure 6 Cisco Aironet 2 4 GHz MIMO Wall Mounted Omnidirectional Antenna AIR ANT2440NV R 10 78 19616 01 Installing the Antenna MI Figure 6 Wall Mounting MOUNTING SURFACE WALL BRACKET 205867 Stepb Slide the mounting bracket onto the wall bracket and secure it in place optional with the two screws provided Figure 7 Figure 7 Attaching Mounting Bracket to Wall Bracket WALL MOUNTING BRACKET BRACKET l 1 i i L 205868 Once the antenna is secured on the wall you can adjust the azimuth and elevation Step6 To adjust the azimuth and elevation loosen the bolt that attaches the antenna bracket to the mounting bracket Figure 8 Azimuth can be adjusted 90 degrees Elevation can be adjusted 15 degrees and 35 degrees Cisco Aironet 2 4 GHz MIMO Wall Mounted Omnidirectional Antenna AIR ANT2440NV R 78 19616 01 EE BE installing the Antenna Figure 8 Azimuth and Elevation Adjustment AZIMUT ADJUST WITH ANTENNA ELEVATION ADJUST WITH ANTENNA 254345 Mounting on a Ceiling Step 1 Step 2 Step 3 Step 4 To mount the antenna on a ceiling follow these steps Drill a hole in the ceiling a
