The antibandwidth problem is to label vertices of a nvertex graph injectively by 1, 2, 3,... n, such that the minimum difference of labels of adjacent vertices is maximised. The problem is motivated by obnoxious facility location problem, radiocolouring, work and game scheduling and is dual to the well known bandwidth problem. We prove exact results for the antibandwidth of complete kary trees, k even, and estimate the parameter for odd k up to the second order term. This extends previous results for complete binary trees.
