The response of a gravitational wave antenna to linear, mixed, and randomly polarized sources is studied as a function of sidereal time, source coordinates, and antenna location and orientation. We find that the gravitational signals reported by Weber cannot be highly polarized tensor radiation coming from a single source at the Galactic nucleus.
