Tallysman TW3600

TW3600 Permanent Mount Iridium Antenna

The TW3600 by Tallysman Wireless is a professional grade, permanent mount, passive right hand circularly polarised antenna for the 1616 to 1626.5 MHz frequency band, specially designed to maximise the performance of Iridium voice and data modems.



The TW3600 features a high performance dual-feed patch element that provides great axial ratio (3dB max) over the entire Iridium frequency band, thus signals at the band edges remain truly circular, unlike the response of single feed antennas.

The TW3600 is housed in a permanent mount industrial-grade weather-proof enclosure and comes with a TNC Jack (female) connector, allowing for the Iridium modem to be mounted out of the elements and reach, and still providing excellent Iridium signal coverage.
