To aid in Canadian Search and Rescue efforts, a 1.61 GHz satellite communications system has been proposed for the CH-146 Griffon helicopter. Its installation requires the placement of another antenna on an airframe that is already populated by more than 20 antennas. A structural analysis has identified only three possible antenna locations. The Multi-Level Fast Multipole Method code of the computational software FEKO has been used to determine the best antenna location based on the radiation patterns and rotor modulation. The near-field and surface current levels have been simulated to determine which of the existing antennas are at risk of experiencing conducted and radiated interference.
