The 'Stream 2' - MA.209 GPS/GLONASS/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 Two is unique in the market as it combines the highest possible efficiency and peak gain for GPS/GLONASS/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 3G 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 Two works best when attached to plastic or glass, but can also be used on metal if some foam spacing of 40mm or more is added.
