What technique helps to minimize RF “hot spots” in an amateur station?
The correct answer is C: Bonding all equipment enclosures together. A technique that helps to minimize RF 'hot spots' in an amateur station is to bond all equipment enclosures together. Bonding ensures all equipment is at the same potential, preventing RF voltage differences (hot spots). For amateur radio operators, this is essential for RF safety. Understanding this helps prevent RF hazards.
Exam Tip
Minimize RF hot spots = bond all equipment enclosures together. Think 'B'ond = 'B'rings 'E'nclosures to 'S'ame potential. Bonding ensures all equipment is at the same potential, preventing RF voltage differences (hot spots). Not metal enclosures alone, not surge suppressors, not filters - just bonding.

Real-World Application
You bond all equipment enclosures together with heavy wire or strap. This ensures all equipment is at the same RF potential, preventing RF voltage differences (hot spots) that could cause RF burns. Bonding is essential for RF safety in amateur stations.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Building equipment in metal enclosures doesn't minimize hot spots - metal enclosures are good, but bonding is what prevents hot spots. Enclosures alone aren't enough.
Option B: Incorrect. Surge suppressor power outlets don't minimize RF hot spots - they protect against power surges, not RF. Surge suppressors don't help with RF.
Option D: Incorrect. Low-pass filters on feed lines don't minimize RF hot spots - they reduce harmonics, not hot spots. Filters don't prevent hot spots.
