Here's the original arrangement. It worked fine except for one problem. The Sat Compass is all the way aft. It's got a good clear view of the sky which is good. The various devices are show in the picture.
|Original stinger arrangement|
|Sooting suggests we are too close to the exhaust stack.|
|New stinger arrangement|
Doing this was actually a royal pain in the ass. The N2K cables for each device thread through the stinger and down the stack. And they only come out through the top, so two of the three had to be pulled all the way out, then snaked back through, and down the stack. This also included removing the connectors at the lower end, then reinstalling them after re-routing. But now it's done. One more thing off the list.
