Wireless APs 26XX and 36XX

HiPath Wireless Controller, Access Points and Convergence Software V7.11, User Guide 501
If Alternate antenna diversity is used for Tx or Rx, then the same antenna
model must be used as left and right antennas. In addition, if cables are used
to connect external antennas, the cables must be of the same length and
similar attenuation. If these rules are not respected, antenna diversity will not
function properly and there will be degradation in the link budget in both
directions.
You can choose to install only one antenna provided that both Tx and Rx
diversity are configured to use that antenna and only that antenna. You can
choose to install one antenna for 11b/g band and one antenna for 11a band,
provided that the antenna diversity is configured appropriately on both radios.
Sensor support
Changing the antenna on sensors is not supported (at this stage) for the following
reasons:
The sensor factors the antenna gain and pattern in its calculations and
therefore it needs to know the antenna type and gain.
The sensor operating in mitigation mode becomes a transmitter and must
obey the same CTLs as the normal AP software.
Neither the sensor nor the HiPath Wireless Manager HiGuard support
configuring the antenna.
B.2.3 AP3620 external antenna AP
Approved external antennas
The AP3620 external antenna APs can also be used with optional certified
external antennas:
Any unused antenna ports must be terminated when an external antenna is
used with the AP3620.
