ISR School: Suspension Cable

Previously, we wrote about how the so-called platform above the 305-m Arecibo main reflector is suspended from three towers and how it is accessible by catwalk or cable car. But what kind of cables are needed to suspend the 900-ton platform with all the steering mechanics and the transmitter/receiver systems?

There's an exhibit near the observation platform for visitors, just outside the lecture room where this year's Joint US-EISCAT Incoherent Scatter Radar School took place. These cables thicker than an arm, something like five inches or so. The rest of their vital statistics you can read on the sign (click to enlarge).
