TW2643A Single Band GNSS Antenna with Receive-Only Iridium

Tallysman TW2643A Single-Band GNSS Antenna with Receive-Only Iridium

The TW2643A single band GNSS antenna with receive-only Iridium from Tallysman supports coverage for GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS, QZSS, EGNOS & MSAS) and Iridium (PNT receive-only).



Designed for indoor timing applications relying upon both GNSS and Iridium’s PNT signal, the TW2643A single band GNSS antenna with receive-only Iridium features a high performance dual-feed patch element that provides great axial ratio over the entire bandwidth. The signals at the band edges remain truly circular, unlike the response of single feed antennas.

The TW2743A is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
