A big aerial, while desirable for trans- mitting or for receiving distant stations, lis not needed for receiving powerful, nearby stations, and it prevents sharp tuning. Use a short aerial (not over seventy-five feet) and keep it clear of all grounded metal objects, such as tin roofs, gutters, and telephone and electric wires. Better yet, use an indoor loop aerial, with one end connected to the aerial binding post of the receiver and the other to the ground, and disconnecting the regular ground.
