  If no light Higgs boson exists, the interaction among the gauge bosons
becomes strong at high energies (~1TeV). The effects of strong electroweak
symmetry breaking (SEWSB) could manifest themselves indirectly as anomalous
couplings before they give rise to new physical states like resonances. Here a
study of the measurement of trilinear gauge couplings is presented looking at
the hadronic decay channel of the W boson at an e-gamma - collider. A
sensitivity in the range of 10^{-3} to 10^{-4} can be reached depending on the
coupling under consideration.
