The J8999A may be mounted at interior or exterior locations. A line of sight signal path works best for point-to-point links. Although 5 Ghz signals penetrate cubical dividers and interior partitions with little attenuation, reinforced block walls, banks of metal cabinets, or steel shelving may attenuate signals or cause multipath, a condition where reflected signals interfere with the primary signal. Because antenna beamwidth is narrow, it is important to aim the antenna accurately during installation, in order to provide optimum gain and best performance.
