A configuration is described to measure the effect of the plasma produced by an arcjet thruster on a reflector antenna. The diagnostic consists of a small movable rf probe coupled to a Hewlett--Packard 8510 network analyzer. Because the perturbation is expected to be small ({lt}10{degree} phase shift), wall reflections are an important consideration. To minimize their effect we use Fourier transform gating techniques.
