2602E antennas

[Kyle Morrison]

Does the 2602E have any internal antennas? I'm short on external antennas (air-ant2524dw-r). I'm also wondering which antenna port should be used if you are only using one antenna. I assume it's A but can't find anything in the docs.

None.

A but turn off Diversity.  It's is not a recommended long-term solution, just a note.

There isn't any internal antennae for 2602E.

Beginning in privileged EXEC mode, follow these steps to select the antennas the wireless device uses to receive and transmit data:

	Command	Purpose
Step 1	configure terminal	Enter global configuration mode.
Step 2	interface dot11radio {0 | 1 slot / port }	Enter interface configuration mode for the radio interface. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1. The 802.11n 2.4-GHz radio is radio 0 The 802.11n 5-GHz radio is radio 1.
Step 3	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. Note For best performance with two antennas, leave the 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 | abc-antenna | abcd-antenna}	Set the transmit antenna to diversity, left, or right. Note For best performance with two antennas, leave the 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 6	end	Return to privileged EXEC mode.
Step 7	copy running-config startup-config	(Optional) Save your entries in the configuration file.
