I didn't realize that I needed to buy my own VOR antenna for the build. I will want to be able to use VORs in case the GPS network goes down some day, plus I enjoy using them currently in my Piper Cherokee when I don't want to just follow the magenta line. I bought a RAMI AV-520 so I can install the base station, then go back and install the antenna leads a little more easily. That was the plan, anyway. Now that I've received it, I see that there are set screws to hold the antennae in place. I just need to make sure that I can access them after the skin is in place. Either that, or Locktite will be my friend!
