Abstract
An aircraft warning marker for use on a suspended high voltage wire is provided. The marker is composed of a substantially smooth, continuous electrically insulating body and a substantially electrically continuous electrically conducting layer disposed adjacent substantially the entire outer surface of the electrically insulating body. The insulating body and the conducting layer have a sufficiently low combined weight so that the marker is supportable on the wire. The electrically conducting layer of the marker is intended to be electrically connected to the wire.
