*Question E9H06:
What indicates the correct value of terminating resistance for a Beverage antenna?*  

*Correct Answer is  D: Minimum variation in SWR over the desired frequency range*  

### AI Response: (may contain errors)  

To determine the correct value of terminating resistance for a Beverage antenna, we focus on minimizing the variation in Standing Wave Ratio (SWR) over the desired frequency range. 

### Correct Answer: D - Minimum variation in SWR over the desired frequency range

- **Explanation**: 
  - A Beverage antenna is a type of long wire antenna that is designed for low-angle radiation and is often used for receiving. The terminating resistor is crucial because it helps to absorb the signal at the end of the antenna, preventing reflections that can cause variations in SWR.
  - By minimizing the variation in SWR, we ensure that the antenna operates efficiently across the desired frequency range, which maximizes the antenna's performance and signal reception.

### Why the Other Choices are Incorrect:

- **A: Maximum feed point DC resistance at the center of the desired frequency range**  
  - This choice is incorrect because the feed point resistance does not directly correlate with the performance of the antenna in terms of SWR. The focus should be on the terminating resistance rather than the feed point resistance.

- **B: Minimum low-angle front-to-back ratio at the design frequency**  
  - This option is not relevant to the terminating resistance. The front-to-back ratio is a measure of the antenna's directivity and is not directly influenced by the terminating resistor. The goal is to optimize SWR, not the front-to-back ratio.

- **C: Maximum DC current in the terminating resistor**  
  - This choice is misleading. While the current through the terminating resistor is important, maximizing it does not ensure optimal performance. Instead, the focus should be on the impedance matching and minimizing SWR.

### Useful Rule of Thumb:
- For optimal performance of a Beverage antenna, the terminating resistor should typically match the characteristic impedance of the antenna system (often around 300 ohms) to minimize reflections and ensure a low SWR across the operating frequency range. 

In summary, the correct approach to selecting the terminating resistance for a Beverage antenna is to focus on minimizing SWR variation, which directly impacts the antenna's efficiency and effectiveness in receiving signals.
