We consider a multifrequency inverse source problem for time-harmonic acoustic or electromagnetic waves. Assuming that far field measurements of the wave radiated by a collection of compactly supported sources are available across a whole frequency band but only at a few observation directions, we develop a non-iterative reconstruction scheme to locate the support of the sources. The method produces a union of convex polygons that approximate the positions and the geometry of well-separated source components.
