Late Night Antenna Math

It's late, and I'm doing math, there ought to be a law :-)

I'm doing this partially because I want to know if I'll be able to study after work in the spring. How does my mind handle math in the wee hours of the night?

I'm not real sure, but I've been having some fun modeling some antennas!

Sometimes it helps me to see what the antenna looks like, then I can write down some numbers, and enter them into XNEC2C.
Main thing I've learned tonight is that you need to make sure you are running your wires the right way when you fiddle with their lengths!
I've included a github gist for this antenna below.

	CM Small Antennas for Small Spaces, Appendix A
	CM I'm pretty sure this is the correct way to model this antenna!

***EDIT*** It should be noted that units in the file above are in Meters, not feet. Also: I think there's a way to go from XNEC2C to EZNEC, if you know something about the NEC Cards. I don't understand the process though.
