The Tallysman TW1500 employs their unique Accutenna technology in a low cost dual feed, passive Left Hand Circularly Polarised antenna (LHCP) for the 1610 to 1620 MHz frequency band, specifically designed to maximise the performance of the Globalstar™ STU (Simplex Transmit Unit) modems.
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.
