  The ATLAS detector at the LHC is used to search for high-mass states, such as
heavy charged gauge bosons (W'), decaying to a charged lepton (electron or
muon) and a neutrino. Results are presented based on the analysis of pp
collisions at a centre-of-mass energy of 7 TeV corresponding to an integrated
luminosity of 4.7 fb-1. No excess beyond Standard Model expectations is
observed. A W' with Sequential Standard Model couplings is excluded at the 95%
credibility level for masses up to 2.55 TeV. Excited chiral bosons (W*) with
equivalent coupling strength are excluded for masses up to 2.42 TeV.
