An induction radio's transmitting antenna may be an air-cored loop or a ferrite-cored solenoid. Because there are so many variables involved it is difficult, in the general case, to compare the two types of antenna and it is not possible to state, unequivocally, which type of antenna will perform better. However, in specific practical situations, a comparison is possible. In this article David Gibson describes one such case.
