Depending on what AP you are connecting to and distance you might look at an antenna with higher gain such as the ANT-2x2-5314. This is a 30deg antenna and 14dBi gain. This has a narrow focus so it does not "hear" as much noise from the environment. Keep the connector types in mind. Outdoor antennas will have Type-N connectors, as do our outdoor APs where indoor APs use RP-SMA connectors so you need an adaptor.
