Leave it to Jim to bring up the good old days when TV production used TV81
http://www.tvcameramuseum.org/camera...v81a.htm#notes The days of iron men needed to pull this cable for each camera are long gone. The connector in the link is about 2.5-3 inches in diameter and the cable came on powered reels in the belly of the truck for sports trucks. TV81 cable is 1.75 inches in diameter and a single person could only carry about 100' coil on their shoulder. Of the 81 wires, there were six coaxes and several power wires carrying 120 volts or more depending on the camera. The wire had a 1/8" rubber jacket which made it even heavier and sticky when pulling or coiling the cable.
