There are many factors to consider when deploying an external antenna with your
access point. The location of your AP, its distance from the antenna, how the
antenna is mounted, and the type of cable used all contribute to the effectiveness
of your installation.
For best results, a complete site survey is required before deploying your access
point and external antenna. 3Com recommends that installation be performed
only by qualified personnel.
When installing your 3Com access point, follow the instruction that came with
your unit for mounting and set-up procedures. For the 3Com external dual-band
antenna, be sure to follow the instructions included with the antenna for
mounting and connection procedures.
For an external antenna to work properly, it must be connected to the AP using a
special low-loss cable. "Selecting 3Com Low-Loss Cables" describes how to select
an appropriate cable for your application.
All 3Com IEEE 802.11 dual-band external antennas must be used with 3Com
antenna cables. 3Com antenna cables provide a certified connection between the
3Com access point and the 3Com antenna. The cables also provide proper
connectivity between the SMA jack on the access point and the N-type jack on the
antenna.
Note that external antennas and cables are sold separately.
3Com offers ultra-low-loss cables to maximize the performance of your wireless
installation in either 2.4 GHz or 5.0 GHz applications. Note that you should always
choose the shortest cable that is appropriate for your installation.
Refer to Table 5 to select the correct length of cable you will need to connect your
external antenna to the access point. All cables are terminated on one end with an
N-type connector for connection to the external antenna, and an SMA connector
on the other end for connection to the AP.
