The TW2505 by Tallysman Wireless is a professional grade, embedded, passive left hand circularly polarized antenna for the 1610 to 1620 MHz frequency band, specifically designed to maximise the performance of the Globalstar™ STU Modem.
The TW2505 features a high performance dualfeed patch element that provides great axial ratio (3 dB 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 50 mm diameter ground plane and with a 15 cm RG174 cable.
