  A new anode support structure for the spherical proportional counter is
presented that incorporates a resistive correction electrode made of glass.
This electrode improves the electric field homogeneity versus angle while
suppressing the probability and intensity of sparks compared to non-resistive
alternatives. The configuration of the correction electrode was optimised with
simulations. Such support structures have been constructed and measurements
have demonstrated homogeneous response of the detector and operational
stability. A measurement of the resistivity of the glass used is also
presented.
