We investigate the scope of the Large Hadron Collider in probing the parameter space of a 4-site model supplemented by one composite Higgs state. We concentrate on the yield of mixed'' diboson production giving three leptons and missing (transverse) energy in the final state, i.e., events induced via the subprocess q (q) over bar' -> l(+) v(l)l'(+) l'(-) + c.c., where q, q' are quarks and l, l' = e, mu in all possible combinations, a signature which enables the production in the intermediate steps of all additional-with respect to the standard model-neutral and charged gauge bosons belonging to the spectrum of this scenario. We not only find this channel to be accessible over the background but also show that, after a dedicated cut-based analysis, kinematical reconstruction of all such resonances is always possible. We finally compare the yield of the mixed diboson mode to that of the charged'' diboson one and find that the former is of lesser scope than the latter at smaller gauge boson masses but it overcomes it at higher values, thereby revealing itself as a viable search mode covering new regions of parameter space.
