~The TW3870 / TW3872 employs Tallysman’s unique Accutenna® technology covering the GPS L1/L2, GLONASS G1/G2, GalileoE1, BeiDou B1, and SBAS (WAAS, EGNOS & MSAS) frequency bands. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. This antennasets a new price/performance standard in its category.

The TW3872 has a pre-filter which increases the antenna’s immunity to high amplitude interfering signals, such as LTE and other cellular signals.
