You are bidding on a Cisco Aironet 5GHz 7-dBi Diversity Patch Antenna w/RP-TNC Connectors. AIR-ANT5170P-R.

Because the antennas transmit and receive radio signals, they are susceptible to RF obstructions and common sources of interference that can reduce throughput and range of the device to which they are connected. Follow these guidelines to ensure the best possible performance:

• Mount the antenna to best take advantage of its propagation characteristics. Mount it as high as possible and oriented so that the cables are pointing down (towards the ground).
• 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 must pass through and still maintain adequate coverage. Consider the following before choosing the location in which to install your antenna:

– Dry paper and vinyl walls have very little affect on signal penetration.

– Solid and pre-cast concrete walls limit signal penetration to one or two walls without degrading coverage.

– Concrete and wood block walls limit signal penetration to three or four walls.

– A signal can penetrate five or six walls constructed of drywall or wood.

– A thick metal wall causes signals to reflect, causing poor penetration.

• Install the antenna away from 5-GHz cordless phones. These products can cause signal interference because they operate in the same frequency range as the device your antenna is connected to.
