- RoHS compliant The TW1600 employs Tallysman’s unique Accutenna™ technology in a low cost OEM dual feed, passive Right Hand Circularly Polarized antenna (RHCP) for the 161 6MHz to 1626MHz frequency band, specifically designed to enhance the signal to noise ratio of communications over the Iridium™ satellite communications network. The wideband dual feed patch element in the TW1600 has an excellent axial ratio across the ent ire Iridium™ bandwidth. Unlike single feed antennas, the TW1600 provides excellent multipath rejection and a truly circular transmission response across the Iridium™ band. The TW1600 includes a built -in 35mm circular ground plane but best performance is o btained with this augmented with a local system ground plane or reflecting surface equivalent to 100mm diameter (DC connection not required). OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules. Dimensions (mm) Micro-Coax cable RG174
