spe - 11 - 8 - 079/ h /as page 2 of 18 ma.501.c.a301111.c305151 1. introduction ma.501 is a combination of high performance gps /galileo and dual band wi - fi (2.4 ? 2.5/5.2ghz) antenna solution for reliab le location information with localised data transfer via wlan, zigbee or wi - fi. this product incorporates the industrys most advanced gps /galileo active ceramic patch technology (xtremegain?) allowing for gains of up to 300% in accuracy compared to tradit ional antennas. time to first fix is under 1 minute with all of the industry leading gps /galileo receivers. xtremegain technology means the antenna has been tuned for the hercules environment giving you the optimum antenna solution to enable elimination of data gaps. the 2.4/5.2ghz antenna inside has also been tuned for this enclosure; hence performance is excellent at all bands meaning the antenna works worldwide. it was d esigned mainly for commercial vehicle and outdoor equipment installations, with e xtra thick threads, with the cables exiting through the bottom for ease of install. durable and robust uv resistant pvc housing is resistant to vandalism and direct attack. it is designed for covert mounting as it is only 3cm high when mounted, thus compli es with the latest eu directives for height restrictions. the antenna housing is completely waterproof to ip67, and also to ip69k, which means it is waterproof against high pressure water jets used in industrial environments for cleaning. 1.1. features gps / galileo ? high lna gain up to 32 db 2 db ? miniaturized C diameter 49mm ? low noise (1.5 db max) ? resides in its own chamber and is tuned for the hercules environment to enhance performance wlan / wi - fi ? advanced dual - band antenna for worldwide applica tion ? tuned for the hercules environment to enhance performance other ? weatherproof (ip67 & ip69k ) with robust foam s eal ? quality textured covert and low profile design
