Tallysman Magnet Mount Globalstar™ Certified STU Antenna


The TW2500 is a professional grade, magnet mount, passive left hand circularly polarized antenna for the 1610 to 1620 MHz frequency band, certified and specifically designed to maximize the performance of the Globalstar™ STU (Simplex Transmit Unit) Modem.

The TW2500 features a high performance dual-feed 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 TW2500 is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, with threaded base holes for screw down attach. It is available with a 50 cm cable, allowing for the STU modem to be mounted out of the elements and reach, and still providing excellent Globalstar™ signal coverage.
