sp e - 16 - 8 - 068/a/wy page 2 of 39 1. introduction the ma252 sentinel 2in1 lte and gps/glonass/beid ou l1 a ntenna is an omni directional, fully ip67 waterproof external m2m antenna for use in telematics, transportation and remote monitoring applications worldwide. it is designed 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. its 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 responder and emergency services a utomotive 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 del ivers powerful performance for worldwide 4g lte bands at 700mhz/800mhz/1700mhz/1800mhz/2600mhz , plus gps - glonass - beidou for next generation location accuracy . 4g wireless applications demand high speed data uplink an d downlink. high efficiency is necessary to achieve the required signal to noise ratio and throughput required to solve these challenges. taoglas also takes care to have high isolation between the two mimo antennas to prevent self - interference. low loss cables are used to keep efficien cy high over long cable lengths.
sp e - 16 - 8 - 068/a/wy page 3 of 39 the ip67 waterproof housing measures just 139*76*14mm with 3m foam adhesive. the antenna can be mounted internally or externally on a vehicle. the lte coaxial cable is 2m low loss cfd - 200 with sma(m) connectors. the gp s - glonass - beidou cable is rg - 174 with sma(m) connector. customized cable and connector versions are also available. the antenna also comes in a 3 in1 2* lte mimo and gnss or a single lte only variant. contact your regional taoglas sales office for support.
