Reflectivity measurements from 400 Mc to 10 k Mc/sec on 2200 A thick aluminum deposited on 1/2-mil-thick Mylar film show this material to be very good reflector of radio waves; measurements made under conditions of stress and temperature encountered by communications sphere, such as Project Echo (1960 Iota), showed very little deterioration of high reflectivity.
