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.
