In this paper we propose a simple reference test object which is to be used as a set up verification device to be tested before High Intensity Radiated Field (HIRF) measurement campaigns on aircraft. This reference object has been designed to take into account both EM and mechanical requirements. It therefore ensures a good level of sensitivity and reproducibility of a reference measured transfer function between the incident E-field and an internal induced current. This object has been calibrated in laboratory using a strip-line which enables to fully control the incident EM field. Finally tests in open test site conditions have been carried out in order to provide reference transfer functions.
