Tallysman TW4600 Wideband Dual Feed Iridium Antenna

Tallysman TW4600 Wideband Dual Feed Iridium Antenna

The TW4600 by Tallysman Wireless is a low cost dual feed, magnetic mount, passive Right Hand Circularly Polarised (RHCP) antenna for the 1616 MHz to 1626 MHz frequency band, specifically designed to maximise the performance of Iridium Satellite communication modems.



The wideband dual feed patch element in the TW4600 has an excellent axial ratio across the entire Iridium bandwidth. Unlike single feed antennas, the TW4600 provides excellent multipath rejection and a truly circular transmission response across the Iridium band.

The TW4600 is the smallest dual feed, high performance Iridium antenna available. It is housed in a compact IP67 magnetic mount enclosure. It available with a 50 cm coaxial cable that allows for an Iridium modem to be mounted away from the weather, yet still provide excellent communications coverage.
