Radio flux versus the high-energy γ-ray flux (E> 50 GeV) of the 132 HBL belonging to the 2FHL catalogue. Blue crosses indicate sources detected in the TeV band. The vertical axis on the right reports the muon neutrino flux (in the 0.1−10 PeV band) predicted with the scaling discussed in the text. We also show the names of the brightest sources.
