We have performed a detailed Monte Carlo exploration of the parameter spacefor a warped Higgsless model of electroweak symmetry breaking in 5 dimensions.This model is based on the $SU(2)_L\times SU(2)_R\times U(1)_{B-L}$ gauge groupin an AdS$_5$ bulk with arbitrary gauge kinetic terms on both the Planck andTeV branes. Constraints arising from precision electroweak measurements andcollider data are found to be relatively easy to satisfy. We show, however,that the additional requirement of perturbative unitarity up to the cut-off,$\simeq 10$ TeV, in $W_L^+W_L^-$ elastic scattering in the absence of dangeroustachyons eliminates all models. If successful models of this class exist, theymust be highly fine-tuned.Comment: 26 pages, 7 figures; new fig and additional text adde
