This antenna is the original Cisco 2.2dBi unit fitted to access points like the AIR-1231b/g. It's a good quality, good performing antenna. If you need one of these it's either because your regular stockist has none, or someone has pinched the antenna from your access point ;-) Don't worry this is the original replacement!
