TW4600 Wideband Dual Feed Iridium Antenna

TW4600 Wideband Dual Feed Iridium Antenna

Manufacturer: | Categories: ,

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



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

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