سؤال 186

What technique helps to minimize RF “hot spots” in an amateur station?

  1. Building all equipment in a metal enclosure
  2. Using surge suppressor power outlets
  3. Bonding all equipment enclosures togetherپاسخ درست
  4. Placing low-pass filters on all feed lines

توضیح

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.
