	The VEPP-5 injection complex serves to obtain high-intensity electron and positron bunches for injection into colliders of the Institute of Nuclear Physics SB RAS. The old RF System operated at 700 MHz - the 64-the harmonic of the revolution frequency. Due to the large beam length from LINAC up to 70% of the particles were lost during injection. Therefore, in 2015, the decision was made to install into the ring the new RF cavity operated at the first harmonic of the ring revolution frequency of 10.94 MHz. To reduce the geometric dimensions, ferrites were used in the cavity. The RF cavity was manufactured, an RF power amplifier and a new RF control system were prepared. After testing the RF system at the stand, in August 2017 the RF cavity was installed instead of the former 700 MHz cavity. The new RF system is now in operation since September 2017. The paper presents main features of the cavity design and fabrication. RF power amplifier and operation of the control system are described.
