MA208AAB007 Datasheet, PDF (2/18 Pages) List of Unclassifed Manufacturers – GPS and LTE/GSM/UMTS Combination Antenna

2. Introduction
The Stream MA.208 GPS/GALILEO/LTE Cellular antenna is a low profile, heavy-
duty, fully IP67 waterproof external M2M antenna for use by RF professionals in
telematics, transportation and remote monitoring applications. The Stream is
unique in the market as it combines the highest possible efficiency and peak
gain for GPS/GALILEO and all cellular bands in 4G/3G/2G in a low profile
compact format for mounting via high quality first tier automotive approved 3M
adhesive foam.
The patent pending design incorporates internally a custom Taoglas 35mm patch
antenna on an extended integral ground-plane to deliver more than 3.5dBiC gain.
A front-end SAW filter dramatically reduces radiated spurious emissions. The
extended ground-plane used with an innovative internal cellular PIFA also
enables the unique wide-band 4G/3G/2G response to deliver the highest
performance possible, at 3 meters cable length. Nothing else out there comes
close in terms of consistency of efficiency and peak gain at all cellular bands,
with an awesome 70%+ at the LTE 700MHz band, again including 3 meters of
cable loss. High antenna efficiencies are absolutely critical in today’s 4G and 2G
systems to achieving targeted data-speeds and coverage.
All this is done while still maintaining 20dB isolation between antennas. The
Stream uses high-shielded PTFE dielectric ultra low-loss cables that maintain low
attenuation at all frequency bands, and high noise rejection, with an average
loss of only 0.3dB per meter (0.1dB per foot), compared to 0.7dB for RG58 and
1.2dB for RG174. Because of this, the Stream maximizes chances of passing
PTCRB and network approvals first time. The Stream works best when attached
to plastic or glass, but can also be used on metal if some foam spacing is added.
