...Physical Colloquium. "The Radiation from an Antenna," by Professor G. W. Pierce, in the Jefferson Physical Laboratory, Room...
...steel latticework tower supporting wireless antenna is located on each end of the flat runway on the roof of the building. The new aerial is as large, if not larger, than any used in the United States; it is made up of five wires stretching from the 100-foot standards above the Laboratory across Langdell Hall to Walter Hastings Hall, a distance of over 600 feet. A message has been received from Berlin, a distance of 3,000 miles, and several times stations on the Pacific Coast have been heard distinctly...
With the erection of the new antenna over the Cruft Memorial Laboratory, a number of important experiments have been carried on by Professor G. W. Pierce and his assistants. On Wednesday a very distinct message was received from Berlin, a distance of over 3,000 miles, and on several occasions stations on the Pacific Coast have been heard distinctly. The new aerial which was just completed during the recent holidays, is as large, if not larger, than any employed by any other University in the United States, and is made up of five wires stretching from the 100-foot standards...
...floors, roof and stairways are built of reinforced concrete, while the outer walls are of brick and the inner walls of hollow tile blocks. The roof is slated, and has, on the top, a flat runway, on each end of which a steel lattice-work tower for supporting wireless antenna is to be erected. These have not yet been erected, but will be in place in a few weeks. The building contains 25 rooms, for research and instruction work. Five of these rooms are under ground, and will be used as constant temperature rooms. One of these, about...
