Tallysman TW2643POC Magnet Mount Passive Iridium Antenna

Tallysman TW2643POC Magnet Mount Passive Iridium Antenna

The TW2643POC employs Tallysman's unique Accutenna technology in a magnet mount, passive right hand circularly polarised antenna for the reception of all of the GNSS constellations (GPS L1/GLONASS G1/Galileo E1/BeiDou B1) plus Iridum: 1559 to 1626.5 MHz frequency
band. It is certified and specially designed to maximize the performance of Iridium Voice and Data Modems plus the upper GNSS band (1559 – 1606 MHz).



The TW2643POC from Tallysman features a high performance dual-feed patch element that provides great axial ratio (4.5dB max, <1.5dB @ zenith) over the entire Iridium + upper GNSS frequency band, thus signals at the band edges remain truly circular, unlike the response of single feed antennas.

The TW2643POC is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, with threaded base holes for screw down attachment. The TW2643POC is RoHS and REACH compliant.
