desired vertical angle over all of the operating frequency range from
1 to 23 mégacycles,
The transmitting and receiving antennas and the
_ground plane were in mutual perpendicular planes with the plane of the
transmitting antenna oriented 53 degrees to the east of magnetic north,
Ionosphere recorder site (C-97 aircraft)
Same as for Rongerik and Kusale, except that a C-3
ionosphere recorder was used,
This recorder is the same as the C-2,
except for a few modifications and improvements.
The transmitting antenna in the C-97 was a single wire
delta fastened to the lateral extremities of the tail assembly.
OPERATIONAL
Kusaie:
Routine operation until H-15 minutes; thence once per
minute until H + 22 minutes; thence twice per minute, alternating the
receiving and transmitting antennas at the end of each 15 second sweep,
until approximately H + 93 minutes; thence once per minute until H + 8
hours; thence routine,
Rongerik:
Routine until H-15 minutes, thence once per minute until
H + 8 hours; thence rcutine,
C-97 Airborne Station:
This station successfully participated in
this test and some data were obtained,
Recorded data for this station
has not been available for review at the time of this writing due to the
planes return to Hickam AFB for maintenance,
