Tallysman Wireless 33-3710-10-10-0200

The TW3710/TW3712 utilizes Tallysman's unique Accutenna technology, covering the BeiDou B1, Galileo E1, GPS L1, GLONASS G1, and SBAS (WAAS, QZSS, EGNOS & MSAS) bands (1557 to 1606 MHz). It provides a truly circular response across the entire bandwidth, enabling superior multipath signal rejection. It is particularly suited for high-precision applications and also offers excellent out-of-band signal rejection.

Both antennas employ a dual-feed wideband patch element equipped with a two-stage low-noise amplifier: one input LNA per feed, a mid-stage SAW filter to filter the combined output, and a final output gain stage. This configuration delivers superior axial ratio across the entire frequency range, along with excellent phase linearity and tight phase center variation — performance typically comparable to higher-priced antennas.

The TW3712 also features a pre-filter to prevent front-end saturation caused by strong near-frequency or harmonic signals.

These antennas are housed in a through-hole mount, weatherproof enclosure suitable for permanent installation. For non-rooftop installations, an L-bracket or pipe-mount adapter is available (part numbers 23-0040-0 and 23-0065-0, respectively). For non-rooftop installations, a 100 mm ground plane is recommended.
