What indicates the correct value of terminating resistance for a Beverage antenna?
Maximum feed point DC resistance at the center of the desired frequency range
Minimum low-angle front-to-back ratio at the design frequency
Maximum DC current in the terminating resistor
Minimum variation in SWR over the desired frequency range✓Bonne réponse
Explication
Correctly terminated, a Beverage behaves as a matched traveling-wave line: almost nothing reflects from the far end, so its input impedance stays nearly constant and SWR hardly moves across the band. A wrong resistance leaves a reflected wave whose interference makes the input impedance, and therefore SWR, swing with frequency.
