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. ## **Applications** - Iridium™ Satellite Communications Applications - Sea & Land Container Tracking - Military & Security - Fleet Management & Asset Tracking - Marine & Avionics Systems - Law Enforcement & Public Safety ## **Features** - Novel 25mm wide-band dual feed patch - 4.25 dBic Gain on 100mm Ground plane. - Great axial ratio, <3 dB over full bandwidth - Weather proof, low cost IP67 housing - Magnetic mount - Wide range of connector options ## **Benefits** - Truly circular polarized signal transmission - Industrial temperature range - Rugged Design - No-compromise performance for cost sensitive applications - RoHS compliant - Remote Iridium™ modem antenna ## TW4600 Wideband Dual Feed Iridium™ Antenna **Specifications** Over full bandwidth, T=25°C ## **Antenna** Architecture Antenna Gain (100mm ground plane) Axial Ratio (over full bandwidth) Radiated sign Bandwidth (-1dB) Dual, quadrature feeds 4.25dBic ≤3dB 1605MHz to 1635MHz ## **Electrical** Architecture Polarization Gain flatness VSWR (at antenna) Return Loss Bandwidth (-10 dB) Dual Feed Patch -> Hybrid 90° Combiner RHCP ≤1dB, from 1611MHz to 1631MHz <1.5:1 >20MHz ## **Mechanicals & Environmental** Mechanical Size Cable Operating Temp.
