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 2ntenna 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 ground and airr

craft receivers, The signal was both stronger and steadier than that produced by the antennas used on the Pacific rounds,
Drop tests using the two redesigned nose cones were conducted at
Morris Dam on 22 November 1958;

timeseach froma height of 35 feet,
of impact was not controlled,

The assemblies were dropped 5

No parachutes were used 2nd the angle

Both assemblies remained completely dry

on the inside throughout the tests,

One cone was slightly damaged when

it came to the surface under a steel barge, but this was quickly repaired.

The two new nose cones were 2ssembled 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 pertizlly, 2s evidenced by the
Nose cone
