I’m not an electrical engineer, but (both) family members who got electronics qualifications have told me RF phase matching circuits are a PITA to build right, and this antenna is a many-element phased array.

They told me this about 20 years ago and I don’t know what’s changed since then. Presumably someone here knows if it’s still hard or if it became easy since 2001?
