This is a
composite picture of the backing structure of the dish to show the cable
harnessing and plumbing routed along it.
Each twisted
pair for the thermistors and TECs are routed horizontally to a vertical
buss, that come together at the corner of the hex plate of the dish.The plumbing is looped along similar
paths, but it’s exit points are at the middle/side of the dish.
There are 198
thermistor wires, 198 thermal electric cooler wires, and several 1000s of
feet of coolant lines routed on the back of this dish.
