The "Poulsen Wireless Telegraph and Telephone Company" soon was renamed the "Federal Telegraph Company", and would go on to become the most successful organiztion providing arc-transmitter communications.

Wireless Across the U. S.
By E. A. Mayne, Chief Operator, Poulsen Wireless Co.
ALTHOUGH wireless telegraphy on the undamped wave principle has been possible for several years, and communication by the employment of sustained oscillations was successfully demonstrated on the Poulsen system as far back as 1906 between Lyngby, Denmark, and Cullercoats, England, it has been only during the last few months that any determined efforts have been made to utilize the very evident advantages of the undamped wave for commercial purposes.
The Poulsen Wireless Telegraph and Telephone Company, with a capital of $25,000,000, has been recently organized by a group of San Francisco millionaires under the laws of the State of Arizona, for the purpose of entering the commercial telegraph field in the United States. It is planned to establish a service from coast to coast, linking up all the principal cities of the country, and in view of the exorbitant rates charged by the wire telegraph monopoly the promoters are very sanguine of success.
At this writing the Poulsen Company have in regular operation stations at San Francisco and Los Angeles, Cal., and El Paso, Texas, and others are in course of erection at Honolulu, T. H., and Fort Worth, Texas. The El Paso station has only within the last few days been completed and the results obtained have been most satisfactory to all concerned--communication being immediately established during broad daylight with San Francisco. This communication, covering as it does a distance of some 1,250 miles, some 800 of which are over desert, constitutes, it is believed, a world's record for daylight transmission under similar conditions and has been quite impossible of accomplishment under spark systems. The successful operation of the Poulsen system between these difficult points, from a wireless engineering point of view, across territory consisting mostly of dry, sandy desert as in Lower California and Arizona, speaks well for the success of the trans-continental service, and should also demonstrate the possibility of bridging vast spaces in other regions of the earth where communication has hitherto been considered impossible.
The power used at San Francisco and El Paso is 12 and 16 k.w. respectively, although further experimenting will undoubtedly lead to a considerable reduction in the energy required. At both plants the antennae are supported by two 300 foot towers located 370 feet apart and consist of two sets of fans each of 22 wires suspended from a steel cable and guyed laterally. This double fan type of aerial has been found the most suitable by the Poulsen experts. The ground connections are in the form of radiating copper wires buried 4 feet in the sand and extending on one side of the lot into the Rio Grande River and on the other into an irrigation canal. The accompanying photo gives a very good idea of the El Paso station.
It will be observed that the towers are built in sections, each of six feet. The entire construction is of Oregon pine and is bolted to a foundation framework of 12 inch California redwood embedded in the sand. The whole of the lumber arrived on the ground ready for erection, and both towers were erected by R. A. Beebee, construction engineer of the company, in seven weeks, at a labor cost of 87 cents per foot. Each tower is supported by five sets of guys consisting of three-inch steel cables, broken up by circuit breakers of hardwood on 10 feet in the lower and six feet in the upper guys. The towers are calculated to withstand a wind pressure of 100 miles per hour.
