Spectra of Kaluza-Klein gauge fields are calculated at the background of themagnetic fluxbrane throat-like solution of the Type IIA supergravity equations.Magnetic flux plays the role of Higgs scalar generating the electroweak scalemass of non-abelian KK gauge field. The same "flux-Higgs" mechanism gives thescale of the "second mass hierarchy", 0.001 eV, in the spectrum of KKexcitations at the background of the throat deformed in a Reissner-Nordstromway. Gauge coupling constants in 4 dimensions are calculated; they prove to beof the physically sensible values for the EW scale massive modes of the gaugefields and are extremely small for the long range gauge fields. 5D effectiveAction with the flux-generated mass terms of the KK gauge fields associatedwith isometries of compactified subspaces is put down, correspondence of the"classical" KK approach and dual holography approach to the low-dimensionalgauge theories is discussed, and idea of Bootstrap Holography is set forth.
