Parabolic Reflector

This are a reflector for a normal "rubberduck" antenna. The smal cheap antennas.
You need to coate the parabolic with aluminum foil (maybe use a beer can) use super glue to assembly the parts. Put the "rubber duck" antenna in the tube, and thats all. not sure what the gain are, i need to do some calc's first. the math i the parabolic are perfect. and the antenna are in the focal point.
I am applying the scad code so you can inspect it.
I print the prototype now, picture will follow soon.
