Command History

To configure the wireless modem card to use a specified number of receive antennas, use the radio receive-antennasinterface configuration command. To set the antenna number to 1, use the no form of this command.

radio receive-antennas {1 2} no radio receive-antennas

1 2	Specifies whether antenna 1 (main) or antenna 2 (diversity) is used.

Release	Modification

12.0(7)XR	This command was introduced.

12.1(3)XQ1	Support for multipoint radio modem was added.

Usage Guidelines				You can enter this command only when the radio link is down (shut). The command takes effect when
				the link is again active (no shut).

Note				Before this command can take effect, the receive antennas and wireless transverters must
				be available.


Examples				The following example shows how to configure the wireless modem card to use two receive antennas:
				Router(config-if)#radio receive-antennas 2
