The Use of Ground Wires at Remote Control Stations

By utilizing the directional selectivity of subterranean receiving antennas, it has proven possible to install receiving stations in the immediate vicinity of transmitting stations. The proper design of the underground antennas, the construction of the shielded rooms for the receiving sets, and the mode of "remotely" controlling the nearby transmitting station are described in detail. The complete design, layout, and installation of several such Naval "remote" control stations is then given. Their proper mode of use and advantages are considered.
