NOTE
Operation in the European Community and rest of the world may be dependant on securing local licenses,
certifications, and regulatory approvals.
Altitude 350-2d external antenna AP
Optional approved 3rd party external antennas
The Altitude 350-2d external Antenna APs can also be used with optional certified external antennas:
The external antennas on the 350-2d must be identical.
Any unused antenna ports must be terminated when an external antenna is used with the Altitude
350-2d.
Antenna diversity
There are some limitations for using different antennas and Tx/Rx diversity:
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.
Altitude 451 external antenna AP
Optional approved 3rd party external antennas
The Altitude 451 external antenna APs can also be used with optional certified external antennas:
The external antennas on the Altitude 451 must be identical.
Any unused antenna ports must be terminated when an external antenna is used with the Altitude
451.
