spe - 16 - 8 - 066 /a/wy page 2 of 62 1. introduction the ma250 sentinel 3in1 adhesive mount 4g lte mimo and gps /glonass /galileo /bei d ou l1 antenna is an omni directional, fully ip67 waterproof external m2m antenna for use in telematics, transportation and remote monitoring applications worldwide. it is de signed to be mounted directly on glass or plastic in the interior of vehicles. it is the smallest high performance solution in the market, 50% smaller than the previous generation, with higher efficiency and wider bandwidth to cover emerging lte bands . it s performance is comparable with much larger permanent roof mount antennas and now offers a convenient and economical alternative in - cabin mounting solution . typical applications include; hd video over lte first res ponder and emergency services a utomo tive vehicle tracking telematics i t is mounted via high quality , first tier automotive approved , 3m adhesive. in - house world leading dielectric ceramic antenna technology inside allows for smaller size antennas without loss in efficiency . it delivers powerful 2*2 mimo antenna technology for worldwide 4g lte bands at 700mhz/ 800mhz/ 1700mhz/ 1800mhz / 2300mhz / 2600mhz , while allowing fallback to all common worldwide 3g and 2 g f requency bands. the antenna has an output for gps - glonass - gali l eo - beidou for next generation location accuracy . 4g wireless applications demand high speed data uplink and downlink. high efficiency and high gain mimo antennas are necessary to achieve the required signal to noise ratio and throughput required to solve these ch allenges. taoglas also takes care to have high isolation between the two mimo antennas to prevent self - interference. low
spe - 16 - 8 - 066 /a/wy page 3 of 62 loss cables are used to keep efficiency high over long cable lengths. the i p67 waterproof housing measures just 139*76* 14mm with 3m f oam adhesive. the antenna can be mou nted internally or externally on a vehicle . both mimo 1 and mimo 2 coaxial cables are 2m low loss cfd - 200 with sma(m) connectors. the gps - glonass - galileo - beidou cable is rg - 174 with sma(m) connector. customized cable and connec tor versions are also available. the antenna also comes in a 2in1 lte/gnss or a single lte only variant. contact your regional taoglas sales office for support.
