What is the function of a Beverage antenna’s termination resistor?

  1. Increase the front-to-side ratio
  2. Absorb signals from the reverse directionRespuesta correcta
  3. Decrease SWR bandwidth
  4. Eliminate harmonic reception

Explicación

Energy arriving from behind travels along the wire toward the far end, where the termination resistor absorbs it instead of letting it reflect back. Without that resistor the reflected wave would give the antenna a response in both directions.
