TW2643P Single Band Passive GNSS Antenna with Iridium

Tallysman TW2643P Single-Band Passive GNSS Antenna with Iridium

The TW2643P single-band passive GNSS antenna with Iridium supports coverage for GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS, QZSS, EGNOS & MSAS, and Iridium).



Designed to maximize the performance of Iridium Voice and Data Modems, while also supporting the upper GNSS band (1559MHz – 1606MHz), the TW2643P single-band passive GNSS antenna with Iridium from Tallysman 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 TW2743P is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
