Figure 8: Coverage Pattern for AP300 When Ceiling Mounted
Most installations receive the best coverage using the following guidelines:
 Install APs toward the center of the building.
 Place APs about 80 feet apart.
 Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.
 For best coverage, orient antennas as shown in Figure 6.
Attach the Provided Antennas
All AP300s have six external antenna ports, labeled 1 - 6. These units operate with six antennas
attached, even though some configurations don’t use all six. Instead of attaching an antenna, you can
cap unused antenna connectors with 50 ohm Reverse Polarity SMA terminators. (For a list of approved
terminators, see http://www.merunetworks.com/merusupport
.) Meru supplied antennas are suitable
only for indoor use unless they are mounted in an outdoor enclosure (see Mount AP300 in a Hoffman
Enclosure). To achieve the best performance from your AP300, position antennas at a 90 degree angle
relative to each other as shown in Figure 6. The antennas do not have to be oriented exactly as shown
in the figure, but it is important to maintain the relative angles. If for some reason you are unable to
maintain those angles, the network still operates, but you may experience up to 20% drop in throughput
depending on the antenna orientation.
