Using an External Antenna with the Access Point 420
Installation Procedures
Using an External Antenna
with the Access Point 420
5. Reconnect power to the access point.
Note Before enabling the radio with an external antenna attached, be sure to first
configure the access point’s antenna mode and transmit power settings.
4. Configure the Antenna Mode and Transmit Power
Control Limits
Using the Web browser interface, CLI, or SNMP, you must configure the
Access Point 420 to use an external antenna. For more information on access
point configuration, see the Management and Configuration Guide, which
is on the Documentation CD-ROM that came with your access point.
The access point must be set for the type of external antenna that is attached,
either a diversity antenna that connects to both access point antenna connec-
tors, or non-diversity antenna that has a single pigtail connection.
The access point’s transmit power must be limited to conform to local regu-
lations. Use the regional settings for each antenna and radio mode as provided
in the Transmit Power Control tables below.
Caution An improper combination of transmit power and antenna gain may result in
an EIRP power level in excess of the legally imposed limit. The transmit power
reduction required for each antenna in each radio mode is listed in the
following tables. Failure to adhere to these guidelines may violate the radio
