The TW3500 by Tallysman Wireless is a professional grade, permanent mount, passive left hand circularly polarised antenna for the 1610 to 1620 MHz frequency band, specifically designed to maximise the performance of the Globalstar STU (Simplex Transmit Unit) Modem.

Overview

The TW3500 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 TW3500 is housed in a permanent mount industrial-grade weather-proof enclosure and comes with a TNC Jack (female) connector, allowing for the Globalstar modem to be mounted out of the elements and reach, and still providing excellent Globalstar signal coverage.
