    Work during the last three or four years has suggested a method which might prove useful in determining the law of radiation from antennae. There are two ways of arriving at the law of radiation. There is a purely mathematical way, which will be described herein. Starting with the EMF, which can be divided into two components in an infinite number of ways, the author divides the EMF between A and ... View full abstract»

    The three principal methods in use at the present time for determining "radiation resistance," arranged in order of increasing precision, are the following: (a) Inserting in the ground connection of the antenna a noninductive resistance of such value that the current in the antenna is diminished in the ratio of one to the square root of two The additional resistance is then taken as equal to the n...

  • High tension insulators for radio-communication

    The tendency of the age is to cheapen production and reduce the cost of both labor and material, but it is extremely unwise to be sparing of expense where insulation is concerned. In a way insulation may be said to be a keystone to the whole, i. e., if the insulation breaks down the remainder of the parts is useless. At the present time it is impossible to give standard values for the strength of ... View full abstract»

    The problem of insulation in wireless is, as Mr. Hills says, a very important one. Probably every radio-engineer or operator present can cite a case or cases wherein a wireless transmitter or receiver had its efficiency marerially lessened by poor insulation, and those of us actively engaged in wireless should be able to profit by this paper, wlhich covers a considerable scope in few words.

    The operations of the Federal Telegraph Company are described. The present chain of stations of the company comprises those at Seattle, Portland, Medford, Central Point, Sacramento, Phoenix, San Diego, El Paso, Fort Worth, Chicago and others in the USA. The messages have been sent from San Francisco to Chicago, the service is not of the same character as that maintained on the Pacific Coast, which... View full abstract»

    At the request of President Marriott, Mr. Hallborg of the Marconi Company, who has lately returned from Europe, described the Transatlantic Marconi station at Clifden. The power used is 125 kilowatt, of which about 50 kilowatts is radiated from the aerial. Power is supplied by four 5000 volt direct current generators in series. These generators are of special type with slotted commutators and air ... View full abstract»
