  We study the phenomenology of the 4-site Higgsless model, based on the
$SU(2)_L\times SU(2)_1\times SU(2)_2\times U(1)_Y$ gauge symmetry, at present
colliders. The model predicts the existence of two neutral and four charged
extra gauge bosons, Z1,Z2,W1,W2. In this paper, we focus on the charged gauge
sector. We first derive limits on W1,W2-boson masses and couplings to SM
fermions from direct searches at the Tevatron. We then estimate at the 7 TeV
LHC the exclusion limits with the actual L=1 fb-1 and the discovery potential
with the expected L=10 fb-1. In contrast to the minimal (or 3-site) Higgsless
model which predicts almost fermiophobic extra gauge bosons, the
next-to-minimal (or 4-site) Higgsless model recovers sizeable W1,W2-boson
couplings to ordinary matter, expressing the non-fermiophobic multiresonance
inner nature of extra-dimensional theories. Owing to this feature, we find that
in one year from now the new heavy gauge bosons, W1 and W2, could be discovered
in the final state with an electron and large missing transverse energy at the
7 TeV LHC for W1,W2-boson masses in the TeV region, depending on model
parameters.
