Gary, I don't think it really resembles a lattice cage mast, maybe partially. The shape is much stronger, being a dome - not a long tapered mast.
The concept is similar with "horizontal hoops" and 2 diagonal vertical criss-crossings (the fourth course is also vertical). The 4th picture down
in this link - http://www.dieselpunks.org/profiles/blogs/lattice-masts
shows the method sort of (but not the shape). To quote "The masts are
a type of hyperboloid structure", as shown in this link - http://www.dieselpunks.org/profiles/blo ... -oka-river
Also the geodesic shape can be made elliptical, either oblong or oblate.
Umtallguy, yes it's definately more complicated. But the smaller lower frequency domes are not that complicated. Modeling/building one would
first start smaller to become more familiar with the process.
rafterman, I sent you a PM.
