<p>This invention is directed to a method and apparatus for determining at least one property of an earth formation. The present invention accomplishes this objective by using an antenna configuration in which at least one of a transmitter antenna (T1) and a receiver antenna (R1) are oriented in a plane that is not orthogonal to the tool axis. Preferably, either the transmitter or the receiver is mounted in a conventional orientation in a first plane that is normal to the tool axis, and the other antenna is mounted in a second plane that is not parallel to the first plane.
