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.
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.
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.
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.
