Felger

Seconded, would also like a range number output from the calculator, since multiple antennas increase the overall range of the craft's signal.

As an aside, the offset shown above was achieved by moving the model and top/bottom nodes down, leaving the side nodes alone. This achieves some pretty good-looking results: 

A little more tinkering, and I'm starting to understand the issue a bit better. It looks like no matter where the nodes are, the fairing starts at the node radius...
