The table shows the amount ofcurrent in an antenna having a total resistance of 25 ohms whichwould correspond to the telephone shunt readings on a detectorcoupled to the antenna with the degree of coupling capable ofdrawing the maximum amoimt of energy into the detector.^ Shimt readings are very difficult to take even under the bestcircumstances. In a quiet laboratory it has been found possibleto make them agree among themselves with average errors inthe single observations not greater than 10 per cent. In a wire-less station, wi
