Start with the threat, not the catalog
Define which drones, which approach routes, and what consequence you must prevent; that profile drives range, bands, and effector choice.
Survey the site before comparing ranges
Line of sight, mounting height, RF noise, and power availability decide real-world performance more than brochure numbers.
Check the command layer
Multi-sensor sites live or die by their C2 platform: fusion quality, whitelists, zone rules, and evidence export matter daily.
Plan for compliance and lifecycle
Authorization scope, training, spares, and software updates belong in the budget from day one.
