The critical current angular dependences and hysteresis losses of a DyBCO-based coated conductor are studied. It is found that the asymmetry of the critical current angular dependences decreases with increasing magnetic field and/or electric field criterion. The areas of the magnetic moment hysteresis loops differ by 15-20 % for equally deviated from the normal angles, indicating a proportional difference in magnetization losses. Thus, even at high fields, where the critical current angular dependences are apparently symmetric, the asymmetry manifests itself through differences in hysteretic losses. Keywords: DyBCO, anisotropy, asymmetry, angular dependence, hysteresis losses.
