TILT MANAGEMENT
Figures C--3 and C--4 show the relationship between tilt angle, flight
altitude, and selected range. The figures show the distance above and
below aircraft altitude that is illuminated by a 12 inch flat--plate radiator
during level flight with 0_ tilt, and a representative low--altitude situation,
with antenna adjusted for 2.8_ up--tilt.
