<p>It has been shown by Fisher and Austin that the radiation resistance of an antenna decreases rapidly with increasing wave-length to a minimum and then rises again in a linear manner with further increase in wave-length. This increase has been attributed by Austin to dielectric absorption in imperfect dielectrics in the electric field of the antenna. This explanation is verified by the tests now described. An experimental antenna was built in which the bad effects of poor dielectrics in the neighbourhood were avoided, but in which any absorption that might be caused in the ground would be considerably magnified. This antenna consisted of 6 parallel wires at about 0.3 m. above the ground and located at a considerable
