Those things matter, but placement often matters first. Once an antenna or antenna array is installed in a real site, the local geometry begins shaping which signals arrive, which paths dominate, and whether the measurement still reflects the emitter or mostly reflects the environment.</p> <p>This matters even more for multi-sensor security and counter-UAS work because RF installations are frequently placed on rooftops, masts, corners of industrial sites, or utility structures that were not originally designed for clean radio geometry. The result is that an excellent antenna system on a poor site can become a weak detector, a misleading bearing source, or both.</p>
