Spatial Diversity AntennaThe spatial diversity antenna is designed with 2 independent antennas inside. The RE11DS is ideal for use with wireless access points, routers and pc cards that have dual antenna ports. It is ideally suited for IEEE 802.11b/g/n and MIMO wireless LANs, public wireless hotspot applications and other systems operating in the 2.4GHz ISM band.The spatial diversity feature of this WiFi antenna is useful for operating in areas susceptible to the affects of multi-path interference. By providing spatial diversity, the radio's internal circuitry can select between the two receive antennas for better wireless reception. The RE11DS spatial diversity antenna can be installed for horizontal or vertical polarization. This spatial diversity antenna can be wall or ceiling mounted, as well as mast-mounted using U-bolts.Note: This antenna is not intended for use with two separate radios.
