Experiments with Yagis at A&AEE Boscombe Down.

The early promise of the Lancaster on trials and in Service soon led to
its selectlon for special tasks. First from July 1942 was as the carrier
of the Capital Ship (CS) bomb of 5,000 Ib requiring bulged bomb doors.
An early ASV radar was also carried, and some aerials were near the
static source; the Establishment checked the pressure error which caused
an overreading of 8 mph at 152 mph on R5609.

Lancaster I R5609 in July 1942 modified for the anti-shipping role with
Yagi aerial array on the nose and enlarged bomb bay doors for the large
(45 inch diameter) capital ship bomb. An early form of flame damper is
fitted, together with ice guards. The aerials displaced the pressure
head to the port side of the nose, I and at 152 mph the AS1 overread by
8 mph. The aircraft was on loan from No 97 Squadron
