TW2605 Embedded Iridium™ Certified Antenna
The TW2605 by Tallysman Wireless is a professional grade, embedded, passive right hand circularly polarised antenna for the 1616 to 1626.5 MHz frequency band, certified and specially designed to maximise the performance of Iridium™ voice and data modems.
The TW2605 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 TW2605 provides excellent Iridium™ signal coverage, and comes in a compact circular form factor with a built-in 50 mm diameter ground plane and with a 15 cm RG174 cable.
