  Necessary and sufficient conditions are given for a satellite knot to be
fibered. Any knot $\tilde k$ embeds in an unknotted solid torus $\tilde V$ with
arbitrary winding number in such a way that no satellite knot with pattern
$(\tilde V, \tilde k)$ is fibered. In particular, there exist nonfibered
satellite knots with fibered pattern and companion knots and nonzero winding
number.
