0018933 QU 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 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. 106 Nose cone SAN it xo ERE SAN Y ee 106
