TW2500 Globalstar Antenna

Tallysman TW2500 Globalstar Antenna

The TW2500 Globalstar antenna from Tallysman supports coverage for the Globalstar frequency band (1610 MHz – 1620 MHz).



With a dual-feed patch element that provides great axial ratio (3 dB max) over the entire Globalstar frequency band, the TW2500 Globalstar antenna from Tallysman is specifically designed to maximize the performance of the Globalstar Simplex Transmit Unit (STU) modems. The signals at the band edges remain truly circular, unlike the response of single feed antennas.

The TW2500 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.

The TW2500 can also be configured with a 50cm cable, allowing for a Globalstar STU modem to be mounted away from external elements, yet still access excellent Globalstar coverage.
