TW2605 When precision matters.® TW2605 Embedded Iridium™ Certified Antenna Frequency Coverage: Iridium Overview The TW2605 employs Tallysman’s patented Accutenna® technology in an embedded, passive right-hand circularly polarised antenna for the 1616 MHz 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 (3.0 dB 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. Custom tuning, cable length, and connectors are available on request. Applications Features Benefits • Iridium™ Voice and Data Applications • Sea & land container tracking • Safety & security • Fleet management & asset tracking • Marine & avionics systems • Law enforcement & public safety • Custom high-gain 4.25 dBic dual-feed patch • Great axial ratio, 3.0 dB over full bandwidth • 15 kV ESD circuit protection • Small form factor • Available application specific tuning • RoHS, REACH and CE compliant • Excellent circular polarized signal transmission • Industrial temperature range • Rugged design About Tallysman: With global headquarters and manufacturing in Ottawa, Canada, Tallysman is a leading manufacturer of highprecision antennas and components for Global Navigation Satellite System (GNSS) applications.
