20 beam designs on one chart: front-to-back vs gain, colored by family (printed quasi-Yagi / Moxon / bi-quad / metal-CNC) · every dot is a gallery card below — values parsed LIVE from each card's headline (hand overrides where the card quotes a range, e.g. reinforced_metal_yagi F/B ~11–17) · ifa omitted (omni — no F/B) · headline figures only: boundaries/models vary per card (MUR vs PML, ideal vs localized drive), so treat cross-card deltas under ~0.5 dB as noise · regenerate any time with modal run compare_antennas.py — new cards join automatically
