## A Tallysman _Accutenna[®]_ TW2600A Active Ma net Mount Iridium[®] Antenna g 

The TW2600A employs Tallysman’s unique _Accutenna_ technology in a magnet mount, active right hand circularly polarized antenna for the **reception** of all of the Iridum signals: 1615 to 1626.5 MHz frequency band.  It is designed to receive the Iridium signal ONLY (ie not transmit).  This antenna is uniquely designed for indoor timing applications relying upon Iridium’s PNT signal. 

The TW2600A features a high performance dual-feed patch element that provides great axial ratio (4.5dB max, <2dB @ zenith, typical) over the antenna’s bandwidth, thus signals at the band edges remain truly circular, unlike the response of single feed antennas. 

TW2600A Dimensions (mm) 

The TW2600A is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, with threaded base holes for screw down attachment.
