Common volume
Over the horizon: the two horizon-skimming rays intersect at the common volume ≈ 97 m AGL at the midpoint (290 m above the chord, 145 m above the 4/3 horizon), so its Fresnel zone (F₁ ≈ 17.6 m) clears with margin. The geometric line of sight is obstructed — buried 174 m below terrain at its worst point.
