In this talk, we discuss one-loop chiral logarithmic corrections to the $S$ and $T$ parameters in a highly deconstructed Higgsless model with only three sites. In addition to the electroweak gauge bosons, this model contains a single extra triplet of vector states rather than an infinite tower of ``KK" modes. We also discuss the one-loop chiral logarithmic corrections to all ${\cal O}(p^4)$ counterterms in the model other than those contributing to the $S$ and $T$ parameters. This work reported here includes a complete evaluation of all one-loop divegences in an $SU(2) \times U(1)$ non-linear sigma model, corresponding to an electroweak chiral lagrangian in the absence of custodial symmetry.
