## 1. Introduction 

The IAA.01 is a high-performance magnetic mount antenna which is designed specific to communicate efficiently with the Iridium® Satellite Communication system. The IAA.01 has been specifically designed to work on a 30*30cm ground plane. 

The IAA.01 utilises the Taoglas expertise in ceramics by incorporating a ceramic patch tuned specifically for the antenna environment, giving greater stability. The antenna housing is strong, corrosive proof and waterproof to IP67. The magnetic mount allows for easy installation and removal between vehicles or assets, it is easily converted to an adhesive type for greater flexibility. 

Iridium® has certified the IAA.01.121111 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 cable and connector are fully customizable, for more information contact your regional Taoglas Customer Support Team.
