What is the function of a Beverage antenna’s termination resistor?
- A.Increase the front-to-side ratio
- B.Absorb signals from the reverse direction (correct answer)
- C.Decrease SWR bandwidth
- D.Eliminate harmonic reception
WhyA Beverage antenna's termination resistor absorbs signals arriving from the reverse direction. A Beverage antenna's termination resistor absorbs signals arriving from the reverse direction, preventing them from reflecting back down the wire and creating a standing wave that would otherwise turn the antenna's directional, traveling-wave pattern into a bidirectional one, answer B. It doesn't increase front-to-side ratio, doesn't decrease SWR bandwidth, and doesn't eliminate harmonic reception, absorbing the reverse-direction wave is specifically what the termination resistor accomplishes.
