Effective range of the system depended on the altitude of the target. Against a bomber-sized target it was about 10 miles (16 km) at 500 feet (150 m), but increased to 90 miles (140 km) at 20,000 feet (6,100 m). These ranges only applied when all of the dipoles were used in-phase, when connected for height finding the ranges were less.
Testing had shown the maximum detection range on a surfaced submarine was about 5.5 miles (8.9 km), so in a high sea state with the minimum range of 4.5 miles, this left little room for detection. [27] But they did find the sets useful for stationkeeping over the convoys, as well as navigating by looking at the returns from sea cliffs. [25]
