The Spartan MA673 2.4 / 4.9~5.8GHz 3*MIMO antenna is a low profile, heavy-duty, fully IP67 waterproof external antenna for use in 802.11ac high data throughput and video broadcast applications. The Spartan is unique in the market because it combines three 2.4 / 4.9~5.8GHz antenna elements in a heavy-duty antenna with high efficiency in a low profile and high quality aesthetic styled housing. The antenna screws down permanently onto a roof or metal panel and can be pole or wall-mounted. Care has been taken to optimize the isolation at more than 20dB from any one antenna to the other, and radiation patterns are distinct allowing for greater de-correlation, vital factors for optimization of MIMO system efficiency. For industries such as remote monitoring, smart meter systems, construction equipment, public safety at only 40mm high, the Spartan provides an unobtrusive, robust, rugged antenna that is durable even in extreme environments. This specification shows the true performance including 3 meters of cable loss. If cable is shorter antenna performance will increase even more.
