      TW7929 Multi-Constellation Low-Power Triple-Band Antenna


      The TW7929 is a precision-tuned Accutenna® technology antenna supporting triple-band GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2b/B2a, NavIC-L5, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-Band correction services coverage, and is especially designed for precision triple-frequency positioning.

      This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

      The TW7929 features a dual-feed circular stacked patch element. The signals from the two orthogonal feeds are summed in quadrature, pre-filtered in a low loss filter to protect against a wide range of potentially interfering signals, amplified in high linearity, wideband LNA, then band-split, tightly filtered and amplified prior to signal recombination at the output.

      This antenna provides superior multipath rejection and axial ratio, a linear phase response, and tight phase centre variation (PCV), while protecting against intermodulation and saturation caused by high-level LTE 700 MHz signals.  

      The TW7929 is housed in a magnetic mounted, IP67 weatherproof enclosure. A 100 mm diamter ground plane is recommended for optimal antenna performance.

      This antenna is also available in an embedded OEM format (TW3929E), and a through-hole housed version (TW3929).
