spe-14-8-010/b/wy | page 2 of 14 ma.120.a.q108111.p108111 the ma120 antenna is a high performance 450mhz and 868mhz combination thread mount antenna for external use with smart meters, gateways, mesh networks, vehicles and outdoor and indoor assets. it is designed for heavy duty work with extra thick threads. the uv resistant polycarbonate housing is resistant to vandalism and direct attack. at only 29mm high and a diameter of 49mm this unique antenna is the lowest profle and smallest worldwide. the antenna has been tested in free space and on varying sizes of ground-planes, showing good frequency stability, allowing its use in many different mounting environments. the ip67 and ip69k rated housing makes it waterproof against short immersion in water, and also against high pressure water jets used in industrial cleaning. a closed cell foam on base prevents water leaking into mounting hole, while also providing a secure seal to a contoured surface. the standard cable and connector is 1 meter rg316. high quality fep (tefon) jacket is used for the cable. this makes the cable very fexible and able to operate in high temperature environments, corrosion resistant. note this antenna is designed for short range communication in the range of meters to hundreds of meters. for cable lengths longer than 2 meters or where very long communication ranges are desired, apart from needing a higher transmit power from the transmitter, it is recommended to go with much larger high gain stand-alone whip or fberglass omni type antennas, to counteract losses in the cables. 1. introduction
