Tallysman TW2600 Antenna

The TW2600 by Tallysman Wireless is a professional grade, magnet mount, passive right hand circularly polarized antenna for the 1616 to 1626.5 MHz frequency band, certified and specially designed to maximize the performance of Iridium voice and data modems.

It 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.
