A pair of E-shaped shunts are disposed near the top and bottom, respectively, of a deflection yoke for reducing inner and outer horizontal trap errors. A central portion of the E-shaped shunt reduces a ratio between magnitudes of inner and outer E-W pincushion raster distortions.

Deflection yoke with a forked shunt

In a deflection yoke mounted on a cathode ray tube, a pair of silicon steel field harmonic enhancers are placed over rear portions of a horizontal deflection coil of a saddle coil type near an electron beam entrance region of the coils such that portions of the saddle coils are interposed between the field harmonic enhancers and a neck portion of the cathode ray tube. The field harmonic enhancers reduce horizontal coma error by making the horizontal deflection field in the rear portion of the saddle coils more pincushion shaped.
