Hi all
I have a 1240 access point with an aerial plugged into the right bnc connector, the aerial is one of the omni directional tube devices that hangs off the ceiling.
My question is, how should this be set up on the ap, does it need to be in diversity mode or not as its only plugged into one side ?
please help

Hi Carl,
Diversity mode is only used with "two" Antennas. With one Antenna just use the Right hand "Primary" connector.
Hope this helps!

Hi Carl,
Yes, this should be changed when only one antenna is used :)
Here are the commands to reset the Antenna settings to default,diversity (left-right) etc;
antenna
Use the antenna configuration interface command to configure the radio receive or transmit antenna settings. Use the no form of this command to reset the receive antenna to defaults.
[no] antenna {receive | transmit} {diversity | left | right}
Syntax Description
receive
Specifies the antenna that the access uses to receive radio signals
transmit
Specifies the antenna that the access uses to transmit radio signals
diversity
Specifies the antenna with the best signal
left
Specifies the left antenna
right
Specifies the right antenna
Defaults
The default antenna configuration is diversity
Examples
This example shows how to specify the right receive antenna option:
AP(config-if)# antenna receive right
Hope this helps!

If you are using the omni that is designed to hang down from a ceiling, then you are using the wrong antenna for outside. That antenna can get water inside and cause you problems. You need to use the omni that is designed to be installed outside. It has the cable coming straight out of the bottom of the antenna. If yours has the cable coming out of the side of the aluminum then it is the wrong one for outdoor.
AIR-ANT2506 is for outdoor.
AIR-ANT1728 is for indoor.
