 Another attempt to revive the RDF 1.5 concept, today known more generally as bistatic radar, was made in March 1940 when a modified set was mounted in Bristol Blenheim L6622. This set was tuned to the transmissions of the new Chain Home Low transmitters, dozens of which were being set up along the UK coastline. These experiments did not prove successful, with a detection range on the order of 4 miles (6.4 km), and the concept was abandoned for good.
