We report the results of a search for a W{sup '} boson produced in pp(bar sign) collisions at a center-of-mass energy of 1.8 TeV using a 107 pb{sup -1} data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W{sup '}{yields}{mu}{nu}{sub {mu}} and search for anomalous production of high transverse mass {mu}{nu}{sub {mu}} lepton pairs. We observe no excess of events above background and set limits on the rate of W{sup '} boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W{sup '} boson to quark and lepton pairs, we exclude a W{sup '} boson with invariant mass less than 660 GeV/c{sup 2} at 95% confidence level.
