TW3885T Image

The TW3885T from Tallysman Wireless is a Precision-Tuned, Dual-Band (L1/L5) GNSS Timing Antenna. It supports the GPS/QZSS-L1/L5, GLONASS-G1/G3, Galileo-E1/Ea/E5b, BeiDou-B2/B2a/B2, and NavIC-L5 bands. This antenna utilizes Tallysman’s eXtended Filter (XF) antenna technology to mitigate out-of-band signals and prevent saturation of the GNSS antenna, enabling the antenna and attached GNSS receivers to perform optimally. It features a twin circular dual-feed, stacked patch element from where the two signals are combined in a hybrid combiner, amplified in a wideband LNA, band-split for narrow filtering in each band, and further amplified prior to recombination at the output port. This ensures superior multipath signal rejection, linear phase response, and tight phase centre variation.

The TW3885T provides 36 dB of gain and has a noise figure of less than 2.7 dB. It requires a DC supply from 2.5 to 16 V and consumes 32 mA of current. This antenna is available in an IP69K-rated weatherproof through-hole mount enclosure that measures 66 (Dia.) x 21 (H) mm.
