This paper presents an evaluation of the phase shifting excitation and load effects in a Transmission Line Exciting Chamber. This chamber is suggested as an alternative for immunity tests because of the restrictions related to canonical chambers. Here, two methods are used to calculate the E-field: a semi-analytic approach and a numerical one. The semi-analytic method is based on the modal expansion while a software is used for numerical simulations. The results regarding the E-field profile and the related statistical indexes of merit are presented and used to evaluate the chamber performances. Experiments were also conducted in order to evaluate the chamber
