monopulse pair + MIST coupler — simulated install

Monopulse pair + MIST coupler — the simulated install drag = orbit · wheel = zoom · right-drag = pan gold = CNC-loop Σ/Δ pair (one cut part, shared reflector) · green = MIST6002000 DSPSL rat-race (50×50×1, from the uploaded STEP) 200 mm below · black = RG316 pigtails: solder-drill exits, EQUAL lengths, 13 mm-radius bends, in-plane perpendicular pad entry (A→NE, B→SW diagonal pads) · grey = rev-B box shell ghost
