It has now been about seven years since the development of multichannel microwave local distribution systems for the CATV industry first started in 1965, although it seems like yesterday to those of us who have been so heavily involved in this exciting and dynamic field. More progress has been made during the past year, since the 1971 NCTA convention, than in all prior years, insofar as putting multichannel local distribution systems in actual operational day to day use. It can now be said that AML microwave is no longer a developmental technique, but a technique which is essential to progressive cable operators who wish to achieve optimum financial performance for themselves and optimum signal quality for their subscribers.
