An impedance simulator having the capability of simulating the operational impedance characteristics of a whip antenna in open field throughout a given frequency range. The simulator includes a cylindrical chamber of conductive, non-magnetic material coated on the interior surface with a lossy ferrite material. Coaxially mounted on the interior of the chamber is a coaxial conductor having at one end thereof a coaxial connector. The other end of the coaxial conductor has the center conductor thereof extending beyond the end of the outer conductor. This end of the inner conductor has mounted thereon a metallic disk lying in a plane perpendicular to the axis of the coaxial conductor. The utilization device, such as an r-f power source is attached to the coaxial connector. The assembly presents to the utilization device an impedance similar to that of a whip antenna in open field.
