antenna again dB Specifies the resultant gain of the antenna attached to the
device. Enter a value from –128 to 128 dB.
Note This setting does not affect the behavior of the wireless
device; it only informs the management platform on
your network of the device antenna gain.
Step 4
antenna receive
{diversity | left | middle | right}
On the 2600 and the 3600 series,
this command is:
antenna receive
{a-antenna | ab-antenna |
abc-antenna | abcd-antenna}
Set the receive antenna to diversity, left, middle, right, or all.

receive antenna setting at the default setting, diversity.
For one antenna, attach the antenna on the right and set
the antenna for right.
On the 2600 and the 3600 series APs:
a-antenna—to use antenna A
ab-antenna—to use antennas A and B
abc-antenna—to use antennas A, B, and C
abcd-antenna—to use antennas A, B, C, and D
Step 5
antenna transmit
{diversity | left | right}
On the 2600 and the 3600 series,
this command is:
antenna transmit
{a-antenna | ab-antenna |
