Tallysman TW2605

Tallysman TW2605 Embedded Iridium SBD Antenna

The TW2605 by Tallysman Wireless is a professional grade, magnet mount, passive right hand circularly polarised antenna for the 1616 to 1626.5 MHz frequency band, specially designed to maximise the performance of the Iridium SBD Modem.



The TW2605 features a high performance dualfeed 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.
