An object can get very slightly heavier when 200 feet in the air because the air is less dense there and the object experiences less buoyancy. At the same time the object may get very slightly lighter at 200 feet because it is slightly farther away from the center of the earth and the pull of gravity is reduced with elevation in accordance with the inverse square law. Buoyancy would depend on the density of the weight (and how much air is displaced). Gravity depends only on the mass of the weight.

Something might be heavier at 200ft than 0 ft if it was partly floating on air, since the air density would drop significantly in 200ft whereas gravity would not.

Ok, put down the bottle and walk away.

gravity is a constant.
