Am I right in thinking I can leave the insulation on a length of copper wire

obviously it will be longer, maybe 30" instead of 3" but does it have to be
a multiple of a wavelength or something? I am guessing the aerial can be
thin - a coat hanger not necessary here

For a Yagi type beam think in terms of elements at least the diameter
of a pencil. Microbore copper tubing would spring to mind.

I do possess a comercially made beam. If anybody wants the dimensions
email me.
