StackQuickDetune is a fast, no-frills toolbox for RF, optics, and photonics work. See how a radome nudges antenna tuning and adds extra loss before you cut hardware. Pick smart spacing for multi-antenna layouts to lower signal overlap and boost diversity gain. Estimate how low, near-ground installs cut radiation efficiency, then choose a better height or tilt. Preview fog-based loss for-space optical links so you can size power, aperture, and margin. Try etalon settings and mirror strength to get filter sharpness and line spacing that make sense. Rough-in simple anti-reflective stacks at a target color/wavelength with easy index goals. Also explore particle scattering, fiber bend loss, VCSEL spot size, and basic photonic crystal gaps—all quick.
