IMA.01.105111

Specification Part Number: IMA.01.105111 Product Name: External Iridium™ Marine Antenna Features: 1616MHz ~1626.5MHz Iridium antenna Antenna Efficiency > 65% with 1.0 meter standard cable IP67 waterproof Standard 1M CFD-200 coaxial cable Bracket Mount Available Custom cables and connectors available Dims: 108mm Ø90mm RoHS Complaint SPE-14-8-114/C/WY Page 1 of 13 Introduction The IMA.01 Iridium Marine antenna is a high performance, durable, bracket mount antenna which is designed for applications using the Iridium® Satellite Communication system. The durable IP67 rated housing makes the IMA.01 the ideal solution for permanent marine installations. The antenna exhibits excellent efficiency, greater than 65% with the standard 1.0 meter CFD-200 coaxial cable. Iridium® has certified the IMA.01 antenna for commercial use in connection with the Iridium Communications System. Iridium Satellite LLC is the owner of Iridium® and all other Iridium trademarks, service marks, and logos contained herein. The IMA.01 antenna is designed for free air operation, thus no ground plane is required.
