Tallysman Embedded Globalstar™ Certified STU Antenna
Product Order Number:
The TW2505 by Tallysman Wireless is a professional grade, embedded, passive left hand circularly polarised antenna for the 1610- 1620MHz frequency band, certified and specifically designed to maximise the performance of the GlobalStar™ STU (Simplex Transmit Unit) Modem.
The TW2505 features a high performance dual-feed patch element that provides great axial ratio (3dB max) over the entire GlobalStar™ frequency band, thus signals at the band edges remain truly circular, unlike the response of single feed antennas.
The TW2505 provides excellent GlobalStar™ signal coverage, and comes in a compact circular form factor with a built-in 50mm diameter ground plane and with a 15cm RG174 cable.
