Double Cross Antenna Hub and Elbows

These are parts for a 137MHz DoubleCross Antenna. The main hub and conduit elbows which will make the antenna more portable.
Originally designed by NOAA and updated hobby-style at http://imgur.com/a/TiZ41.

We've updated this project to exchange the hub made from epoxy and plumbing parts to a 3d printed part which will be more stable, and durable. We'll be adding some additional instructions soon.
