Common volume
Over the horizon: the two horizon-skimming rays intersect at the common volume ≈ 119 m AGL at the midpoint (357 m above the chord, 179 m above the 4/3 horizon), so its Fresnel zone (F₁ ≈ 18.6 m) clears with margin. The geometric line of sight is obstructed — buried 209 m below terrain at its worst point.
