TerrainAnalysis.analyse was being called with default 0 m antenna heights on both ends of a QSO's path, which makes the knife-edge diffraction math pretend the radios are sitting directly on the terrain surface. Pass 3.048 m (10 ft) for both ant_ht_a and ant_ht_b, and shift the forward/reverse elevation angles to match. This is only a display assumption on /contacts/:id — terrain worker paths computed elsewhere are unaffected. |
