The TW3870E (and its housed version of TW3870) employs Tallysman’s unique Accutenna™ technology which provides truly circular response over the entire bandwidth thereby producing superior multipath signal rejection resulting in higher positional and timing accuracy. The TW3870E covers the GPS L1/L2, GLONASS G1/G2, and SBAS (WAAS, EGNOS & MSAS) frequency bands. The TW3870E offers excellent axial ratio and a tightly grouped phase center. This antenna sets a new price/performance standard in its category.
支持GPS L1/L2, GLONASS G1/G2, 北斗B1,Galileo E1和SBAS (WAAS, EGNOS & MSAS)，75克重。
The OEM TW3870E is supplied with a standard 60mm diameter circular ground plane, with a coaxial cable terminated with a connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
