A new antenna system was devised for the recovery transmitter
consisting of two bent dipoles located on opposite sides of the head and
positioned as far forward as possible so that they would be above the
surface of the water.
This system was tested at Puddingstone Dam near
Pomona, California on 20 November 1958.
The antenna was first sub-
merged, then the head was allowed to float during the test.
Readable
signals were received as far as 5 miles away with both groundand aircraft receivers,
The signal was both stronger and steadier than that pro-
duced by the antennas used on the Pacific rounds.
Drop tests using the two redesigned nose cones wereconducted at
Morris Dam on 22 November 1958.
The assemblies were dropped 5
timeseach from a height of 35 feet.
No parachutes wereused and the angle
of impact was not controlled,
Both assemblies remained completely dry
on the inside throughout the tests.
One conewas slightly damaged when
it came to the surfaceunder a steel barge, but this was quickly repaired,
The two new nose cones were assembled into flight rounds for tests
at NAMTC, Point Mugu, on 2 December 1958,
at a 75° elevation angte and azimuth of 217°,
Both rounds were launched
The second stage of the first
round either failed to ignite, or ignited only partially, as evidenced by the
lack of a contrail and the horizontal range of only 14,200 yards.
