Abstract :
In most ships there is one metallic structure (e.g. a mast) which is considerably taller than any other object on board. It is found that the largest errors in a high-frequency direction-finder installed in a ship are generally encountered when this conductor is in resonance. In this paper all other sources of error are neglected and an investigation is made of the error and blurring caused by a single reradiating vertical mast. The results are applied to assess the suitability of different sites for the d.f. aerial.
