  We study the conformational properties of charged polymers in a solvent in
the presence of structural obstacles correlated according to a power law $\sim
x^{-a}$. We work within the continuous representation of a model of linear
chain considered as a random sequence of charges $q_i=\pm q_0$. Such a model
captures the properties of polyampholytes -- heteropolymers comprising both
positively and negatively charged monomers. We apply the direct polymer
renormalization scheme and analyze the scaling behavior of charged polymers up
to the first order of an $\epsilon=6-d$, $\delta=4-a$-expansion.
