Details
The TW4500 is the smallest dual feed, high performance Globalstar antenna available.
With a compact dual-feed, passive Left Hand Circularly Polarised (LHCP) antenna, the TW4500 is specifically designed to maximise the performance of the Globalstar STU (Simplex Transmit Unit) modems.
The TW4500 has a wide-band dual-feed patch element, providing an excellent axial ratio across the entire Globalstar bandwidth. Unlike single feed antennas, the TW4500 provides excellent multi-path rejection and a truly circular transmission response across the full bandwidth.
The TW4500 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
The TW4500 can also be configured with a 50cm coaxial cable, allowing for a globalstar modem to be mounted away from external elements, yet still access excellent Globalstar™ coverage.
