NOTE
There are four spiral antennas: two left spiral and two
right spiral. The term spiral refers to the winding
direction of the antenna, not left or right side of aircraft.
Always replace antenna with same type removed (left or right
spiral).
One antenna is located in each of the four quadrants of the
aircraft (I, II, Ill, and IV).
CAUTION
All antennas must be mounted in the same way. The radar set
will not work properly if they are not. Each antenna has a
white dot on the rear face. The white dot must be in the
same position for all antennas (up, down, left, or right).
