This paper is a study of the single-$W$ and $W$-pair production at LEP~II. I show that the sensitivity of the single-$W$ production channel on the anomalous trilinear couplings of $W$ is essentially the same as the sensitivity of the channel $e^+e^-\to W^+W^-$. Therefore, even without the reconstruction of the $W$ boson, deviations form the SM predictions on trilinear couplings can be measured at the level of $0.2 - 1$, using single-$W$ production at LEP~II.
