For a list of supported external antennas, see Connecting external antennas in the
MSM3xx / MSM4xx Access Points Management and Configuration Guide.
When using antennas not originally supplied with the AP, it is your responsibility to
ensure that the Transmit power control settings are configured so that the radio will
not exceed permissible power levels for the regulatory domain in which the AP is
operating. Depending on the regulatory domain, the specific antenna chosen, the wireless
mode, channel width, band or channel selected, you may need to configure the radio with
a reduced transmit power setting. When using Automatic channel selection with an
external antenna in the 2.4 GHz band, all channels must be set to the lowest acceptable
value for your regulatory domain.
For specific power limits according to your regulatory domain, consult the Antenna
Power-Level Settings Guide available at
Brand, select ProCurve and search for your antenna).
For example, if you install an external 8 dBi directional antenna, and the maximum
allowed power level for your country is 15 dBm, you may have to reduce the transmit
power level to be in compliance.
If you change the antenna at a later time, you must get the latest version of the Antenna
Power-Level Settings Guide, and again reassess and possibly adjust radio power settings
according to the antenna used.
When setting Transmit power control to comply with information in the Antenna
Power-Level Settings Guide, always set radio power in dBm, and not as a percentage.

Specify the transmission power in dBm or as a percentage of the maximum output power.
When you select Save, percentage values are rounded up or down so that the dBm value is

Note that the actual transmit power used by the radio may be less than the specified value.
The AP determines the maximum power to be used based on the regulatory domain.
Automatic power control
Select this checkbox to have the AP automatically determine the optimal power setting
within the defined power limits (i.e., up to the specified percentage/dBm value).
Specify the interval at which the Automatic power control feature adjusts the optimal
