+ , yA AL 0018933 ings. : 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 iv = lack of a contrail and the horizontal range of only 14,200 yards,
