Abstract

About one hundred years ago, the Radio Corporation of America (RCA) set out to build a complex called Radio Central at Rocky Point, Long Island, NY that was supposed to be the “last word” in long-distance, trans-oceanic radio communication. The facility for transmission was based on a system, remarkable for the time, developed at the General Electric Company (GE), principally by Ernst F. W. Alexanderson, and therefore often referred to as the Alexanderson System for Radio Communication. The main objective for this article is to provide the reader with a simple description of the basic physics, principally the electromagnets, underpinning a few of the key components of this historically important system. In addition, the circumstances that made RCA decide to build this facility as well as those that caused RCA to eventually limit its development are discussed.

100年前的远距离无线电通信：中央电台的亚历山大系统

大约一百年前，美国无线电公司（Radio Corporation of America， RCA）着手在纽约长岛的洛基角（Rocky Point）建造一座名为“中央无线电”（Radio Central）的综合体，该综合体被认为是远距离跨洋无线电通信的“最后杰作”。传输设备是基于一个系统，在当时是非凡的，在通用电气公司（GE）开发的，主要是由恩斯特F. W.亚历山大，因此通常被称为亚历山大无线电通信系统。本文的主要目的是为读者提供基本物理的简单描述，主要是电磁铁，支撑这个历史上重要系统的几个关键组件。此外，还讨论了使RCA决定建立该设施的情况以及导致RCA最终限制其发展的情况。

期刊介绍： IEEE Antennas and Propagation Magazine actively solicits feature articles that describe engineering activities taking place in industry, government, and universities. All feature articles are subject to peer review. Emphasis is placed on providing the reader with a general understanding of either a particular subject or of the technical challenges being addressed by various organizations, as well as their capabilities to cope with these challenges. Articles presenting new results, review, tutorial, and historical articles are welcome, as are articles describing examples of good engineering. The technical field of interest of the Magazine is the same as the IEEE Antennas and Propagation Society, and includes the following: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
