3. Attaching the Antennas

Carefully unpack the standard detachable antennas. Screw the antennas on to the antenna 
connectors on the access point and hand-tighten them. After network startup, you may need to 
adjust the antennas to fine-tune coverage in your area. For best results, adjust the antennas so 
that they are perpendicular with the floor and ceiling. 

Connecting Optional External Antennas

The access point has connectors for attaching optional external antennas and antenna cables. The 
tables below list the external antenna and cable models that are certified for use with the access 
point.   

The 3Com antennas are dual-band, which means that they operate in both 2.4 GHz and 5 GHz 
spectra. You can use these antennas with either the 802.11b/g radio or the 802.11a radio. Each 
antenna requires the purchase of a separate antenna cable. For installation instructions, see the 
documentation that is supplied with the antenna.   

CAUTION:

  Do not handle the antenna tips, especially after they are connected to the access 

point. This could lead to electrostatic discharge (ESD), which could damage the equipment.

Note 3CWE586 is required when using any of the external antennas

NOTE: 

Antenna cables introduce loss of the RF signal. Always use the shortest cable that 

your application allows.

NOTE: 

During the installation, connect the antenna to the access point before connecting 

the Category 5 Ethernet cable. This ensures that the access point is not powered on when 
the antenna connections are made.
