The standard detachable antennas supplied with the Access Point 8250 and Access
Point 8750 are suitable for a broad variety of environments. If you require a different
type of antenna for the Access Point 8250 or Access Point 8750, several options are
available by model number from the 3Com Web site (www.3Com.com). (Access Point
8500 does not support interchangeable antennas.)
For each of the antenna models, you will need either a 6-foot accessory cable (model
3CWE480) or a 20-foot accessory cable (model 3CWE481) to provide the transition
from the SMA connector on the access point to the N-type connector on the antenna.
To ensure the physical safety of anyone near the antenna and to prevent damage to the
access point, follow the building codes for antenna installations in your area. Also,
when connecting the optional antenna to the access point, remember to use only the
A-side connector on the access point, on the right when properly installed.
Note
: For FCC regulatory compliance reasons, in the United States, Canada, and
other countries governed by FCC guidelines, external antennas can only be used in
an access point operating temperature range of 15° C - 40° C (59° F - 104° F).
Note
: If the access point is used with an external antenna you must also purchase an
antenna cable. For maximum efficiency, use the shortest antenna cable possible.
Antenna cables induce signal loss, which will limit the radiated power output and
range of the access point. Of the options available, we recommend the 3Com 6-foot
Antenna Cable (3CWE480).
