Frage 386

Which of the following is a characteristic of using a gamma match with a Yagi antenna?

  1. It does not require the driven element to be insulated from the boomRichtige Antwort
  2. It does not require any inductors or capacitors
  3. It is useful for matching multiband antennas
  4. All these choices are correct

Erklärung

A gamma match connects the coax shield to the electrical center of the driven element, which is a voltage null, so the element can be bolted straight to a grounded boom without insulation. It does use a series capacitor, so the claim that it needs no inductors or capacitors is wrong.
