The concept of a local distribution multi channel microwave link to serve as a means of delivering CATV signals from advantageously located head ends or central offices to distribution substations was proposed in early 1965 and implemented through design, FCC licensing on an experimental basis, propagation testing, and now limited commercial use, in a few selected areas.
The system of which I am speaking is the joint Teleprompter-Hughes Aircraft Company experiments now known to the industry as AML, which is the short identification for the multi channel microwave Amplitude Modulated Link.
The purpose of this paper is to deliver to the industry a current status report on AML.
