In this paper all those unicyclic graphs are characterized for which there exists a basis of the kernel that consists only of vectors with entries from {- 1, 0, 1}. Three different characterizations are obtained, based on an algorithmic, an algebraic, and a structural criteria, respectively. Algorithmic construction of such bases is discussed as well
