A coil-carrier half for a saddle-coil arrangement for a cathode ray tube features a front groove for accommodating a saddle-coil winding, a rear groove and also left slots and right slots. Prolongation of the left slots in comparison with the right slots results from the presence, in the rear front-grove wall, at the positions where the left slots open out into the groove, of steps which are greater towards the front than at the fan-out positions of the right slots. In an asymmetrically built coil-carrier half of this sort, turns are introduced in each slot so that they run as far as the prolongation position of the slot. This produces a saddle-coil arrangement which leads to fewer image defects than when a conventional saddle-coil arrangement with symmetrical coil-carrier halves is used.
