A mounting structure for a pair of transducer heads has a base and integral riser beam for forming a rigid inverted T-shaped structure wherein the riser beam extends perpendicularly to a midportion of the base. The transducer heads are mounted on opposite sides of the riser beam. The supporting structure may have a pair of T-shaped profiles extending at right angles to each other. Individual tilt adjustment with or without azimuth adjustment facilities may be provided for each transducer head.
