The Hyperlink HG5816SXP-090 spatial diversity antenna is designed with two identical and independent cross polarized antenna arrays fed via (4) connectors. The HG5816SXP-090 provides high gain with a wide 90° beam-width making them ideal professional quality "cell site" antennas designed primarily for service providers in the 5.8 GHz ISM band. Applications include IEEE 802.11a and 802.11n wireless LAN systems. The HG5816SXP-090 is ideal for use with wireless access points, CPEs and routers that have dual antenna ports and MIMO capabilities.Spatial DiversityThe spatial diversity feature of this antenna is useful for operating in areas susceptible to the effects of multi-path interference. By providing spatial diversity, the radio's internal circuitry can select between the two receive antennas for better wireless reception. In the case of 802.11n or MIMO, two or more spatially or polarization diverse antennas are required for the radio to operate at its highest data rate.Cross Polarized - X-PolEach of the arrays in HG5816SXP-090 feature two independent antennas with cross polarization. This feature doubles the wireless capacity over the same channels. Each array is fed via two N-Female ports, one for +45° polarized and one for -45° polarized signals. This feature makes this antenna ideal for polarization diversity systems.For additional information and complete specifications, click on the data sheet link in the Downloads tab.
