## A Tallysman _Accutenna[®]_ TW2600 Ma net Mount Iridium™ Certified Antenna g 

The TW2600 employs Tallysman’s unique _Accutenna_ technology in a magnet mount, 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 TW2600 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. 

TW2600 Dimensions (mm) 

The TW2600 is housed in a compact, industrialgrade weather-proof, magnet mount enclosure, with threaded base holes for screw down attach.
