I was wondering exactly what defines a metal as parabolic. not being ferrous?

Goodhart9 years ago
A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone or by the locus of points equidistant from a fixed line and a fixed point not on the line. (i.e. a bowl shape constructed in such a fashion as to focus energy {light, radio waves, etc} onto a point at a specific distance from the parabola). Parabolic: An arched shape.

well I know ferrous material blocks signals by absorbing them, not reflecting them so I was wondering if you make a parabolic reflector out of non-ferrous metal.
. Metals are not parabolic. Parabolic refers to a shape (see Goohart's explanation). . Yes. Aluminum (non-ferrous) is commonly used for reflectors and radiating elements.
