*Question G6B07:
Which of the following describes a type N connector?*  

*Correct Answer is  A: A moisture-resistant RF connector useful to 10 GHz*  

### AI Response: (may contain errors)  

The correct answer to the question about the type N connector is:

**A: A moisture-resistant RF connector useful to 10 GHz.**

### Explanation of the Correct Answer:
- **Type N connectors** are designed for high-frequency applications, typically up to 11 GHz, and are known for their durability and moisture resistance. This makes them suitable for outdoor use and in environments where reliability is crucial. Their design allows for a secure connection that minimizes signal loss, making them ideal for RF applications.

### Why the Other Choices are Incorrect:
- **B: A small bayonet connector used for data circuits**  
  - This describes a different type of connector, such as the **BNC connector**, which is commonly used for video and data applications but is not moisture-resistant or designed for high-frequency RF applications like the type N connector.

- **C: A low noise figure VHF connector**  
  - While type N connectors can be used in VHF applications, they are not specifically characterized as "low noise figure" connectors. The term "low noise figure" typically refers to specific RF components like amplifiers rather than connectors.

- **D: A nickel plated version of the PL-259**  
  - The PL-259 is a different type of connector, primarily used for HF applications. While it may have a nickel-plated version, it does not share the same specifications or capabilities as the type N connector, particularly regarding frequency range and moisture resistance.

### Summary:
- Type N connectors are moisture-resistant and suitable for frequencies up to 10 GHz, making them ideal for RF applications.
- Other options describe different connectors or characteristics that do not apply to type N connectors.

This understanding will help you identify the correct characteristics of RF connectors in the Extra Class exam.
