The trensmitting end receiving antennas and the ground plane were in mutual
perpendicular planes with the plane of the transmitting antenna oriented 53°
to the east of magnetic north,
Ionosphere recorder site (C-97 aircraft)
Same as for Rongerik and Kusaie, 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 festened
to the lateral
extremities of the tail assembly.
