Exam Tip
Line A = line roughly parallel to and south of US-Canada border. Think 'L'ine 'A' = 'L'ooks 'A'long US-'C'anada border, 'S'outh. Line A is a geographic boundary roughly parallel to and south of the US-Canada border. Not Atlantic coast, not Mexico border, not Pacific coast - just south of US-Canada border.
Memory Aid
"Line A = line roughly parallel to and south of US-Canada border. Think 'L'ine 'A' = 'S'outh of 'C'anada border. Line A is a geographic boundary roughly parallel to and south of the US-Canada border. Important for understanding frequency restrictions."
Real-World Application
Line A: It's a geographic line roughly parallel to and south of the border between the US and Canada.
