N = 8, d = 14 mm, HB100 at 10.525 GHz, ideal element power \(\cos\theta\). The main-lobe readout is referenced to the broadside peak, so the 30° run reads the scan loss. Orange ticks under the trace mark the instants the source passed each 30°: with a hand-like walk they land unevenly, and the lobe spacing stretches with them while the lobe amplitudes do not move.
