We investigate the collider phenomenology of a left-right symmetricRandall-Sundrum model with fermions and gauge bosons in the bulk. We find thatthe model is allowed by precision electroweak data as long as the ratio of the(unwarped) Higgs vev to the curvature scale is $v/k \le 1/4$. In that regionthere can be substantial modifications to the Higgs properties. In particular,the couplings to $WW$ and $ZZ$ are reduced, the coupling to gluons is enhanced,and the coupling to $\gamma\gamma$ can receive shifts in either direction. TheHiggs mass bound from LEP II data can potentially be relaxed to $m_H \gtrsim80$ GeV.Comment: 21 pages, 11 figures. Minor changes to numerics; replaced with published versio
