Summary

Description
English: This image shows the front-firing antennas of an ASV Mk. II radar as installed on a Royal Canadian Air Force Douglas Digby (B-18 Bolo) aircraft.

Note the shaping of the transmitter antenna, seen just below the bombsight window. It has been bent into a curved shape to closely follow the shape of the aircraft fuselage, using the fuselage itself as a reflector to make a Yagi antenna using only a single wire. Similar "tricks" were used on a variety of ASV and AI radars, but made it difficult to move to different aircraft designs.

This aircraft is part of 751 Squadron RCAF stationed at Rockcliffe (Ottawa). It is not clear whether this is the same aircraft as seen in other images.
