What technique helps to minimize RF “hot spots” in an amateur station?
Building all equipment in a metal enclosure
Using surge suppressor power outlets
Bonding all equipment enclosures together✓الإجابة الصحيحة
Placing low-pass filters on all feed lines
الشرح
An RF hot spot is a point of high RF voltage between two pieces of equipment that are at different RF potentials. Bonding all enclosures together with short, low-impedance straps forces them to the same potential, so no voltage difference is available to develop.
