In this work, we investigate the physical conditions required for efficient neutrino production by combining radio-constrained jet properties with multi-zone emission modeling. We show that efficient neutrino production requires an external radiation field stronger than the magnetic field in the jet frame. This environment not only enhances the efficiency of photohadronic interactions but also suppresses synchrotron radiation from secondary pairs, thereby avoiding overshooting the hard X-ray data.
