We present results from CDF and D\O\ on $W\gamma$ and $Z\gamma$ productions in $p\bar{p}$ collisions at $\sqrt{s}=1.8{\rm TeV}.$ The goal of the analyses is to test the non-abelian self-couplings of the $W$, $Z$ and photon, one of the most direct consequences of the $SU(2)_L\otimes U(1)_Y$ gauge symmetry. We present direct measurements of $WW\gamma$ couplings and limits on $ZZ\gamma$ and $Z\gamma\gamma$ couplings, based on $p\bar{p}\rightarrow \ell\nu\gamma + X$ and $p\bar{p}\rightarrow \ell\ell\gamma+X$ events, respectively, observed during the 1992--1993 run of the Fermilab Tevatron Collider.
