If I take the Element 3 (General) and Element 4 (Amateur Extra) class written tests right away, will they be usable to upgrade my license, or do I need to wait until after Docket 05-235 goes into effect.

Hi,
Making an off-center fed dipole for 20, 40 & 80m amateur radio (yes, I do have appropriate licensing for Australia). I have the right balun made up, but I am not sure what types of wire I can use. The dipole will be 40m long - I have a nice big yard.

Can it be something simple like gal fencing wire?

Does it help to make antennae shaped like a cube or is it better to have them on one plane(flat)?
Are there methods for calculating the size and ratio of the vanes?
Sorry so layman terms I don't know much about aerials.
(but I do know Shinoloa)
Oh the reason I ask is I want to make a cool and functional aerial for my house.
