Rise & Run

Horizontal Run Distance (ft): {{ runFt != null ? runFt.toFixed(0) : '—' }}

Ground Slope Drop (ft): {{ slopeDeltaFt != null ? slopeDeltaFt.toFixed(1) : '—' }}

Optional: Ground transition point (%): {{ transitionPointPercent != null ? transitionPointPercent : '—' }}%

Optional: Ground early slope (%): {{ earlySlopePercent != null ? earlySlopePercent : '—' }}%

Cable Anchoring

Desired Cable Drop (ft): {{ cableDropFt != null ? cableDropFt.toFixed(1) : '—' }}

End Anchor Height (ft): {{ endAnchorHeightFromEndGroundFt != null ? endAnchorHeightFromEndGroundFt.toFixed(1) : '—' }}
