TW1600 Accutenna® Embedded Iridium Antenna


Specifically designed to enhance the signal-to-noise ratio of communications over the Iridium™ satellite communications network, the TW1600 has a wide-band, dual-feed patch element that provides excellent axial ratio across the entire Iridium band.

Unlike single feed antennas, the TW1600 provides excellent multi-path rejection and a truly circular transmission response across the full bandwidth.

The TW1600 includes a built-in 35mm circular ground plane but best performance is obtained with this augmented with a local system ground plane or reflecting surface equivalent to 100mm diameter (DC connection not required).

Tallysman offers custom tuning services to optimize the performance of the TW1600 for any OEM installation environment.
