1. A broad band coaxial load comprising a conductive rod held coaxially within a coaxial support, the coaxial support having a body that includes a round hole with three axial sections, wherein:
a first section comprises a funnel starting from a first side of the coaxial support and having a first section diameter that is equal to a first diameter at an end of the funnel and that decreases in a direction into the coaxial support to a second diameter, the second diameter matching a diameter of the conductive rod,
a second section comprising a plurality of radially oriented contact springs, said plurality having a diameter matching the diameter of the conductive rod, and
a third section comprising a cylindrical hole with a third section diameter matching the diameter of the conductive rod,
wherein the conductive rod comprises, in an axial direction between a first end thereof and an opposing second end thereof:
a first high conductive zone at the first end,
a first resistive zone following and connected to the first high conductive zone, and
a second high conductive zone at the second end, connected to a zone preceding the second high conductive zone and separated from the first high conductive zone by the first resistive zone.
