A Compact Battery Powered Antenna Analyzer For HF To UHF

Step-by-Step Tutorial: How to Use a Compact Battery-Powered Antenna Analyzer for HF to UHF

1. Introduction to the Antenna Analyzer: The antenna analyzer by Feature Tech incorporates features such as a frequency counter, field strength meter, and capacitance measurements in LC mode. It covers frequencies from 1.8 MHz to 430 MHz, similar to the MFJ 259 but at a lower price point.

2. Unboxing and Setup:

   • In the box, you will find adapters (N-type to BNC and N-type to SO239), a DC power cable, and the analyzer itself.
   • The device can be powered by an internal rechargeable battery or regular batteries. To install regular batteries, remove the screws on the case to access the battery compartments.

3. Device Overview:

   • The analyzer has a metal case with a main tuning dial at the bottom.
   • It features up and down buttons for changing bands and push buttons for selecting HF, VHF, or UHF modes.
   • The antenna connection is an N-type connector for optimal performance at higher frequencies.

4. Powering On the Analyzer:

   • Connect the power source and press the red power button to turn on the analyzer.
   • To activate the backlight, press and hold the up button after turning on the device.

5. Operating Modes:

   • Press up to enter antenna analyzer mode or down for frequency counter mode.
   • Holding the down button while powering on activates inductance measurement, while holding the up button enables capacitance measurement.

6. Antenna Analysis:

   • Select the appropriate band using the buttons on the device based on the frequency range you want to test.
   • Turn the tuning control to view real-time SWR readings on the screen.
   • The display shows frequency, band selection, impedance, and SWR readings for monitoring antenna performance.

7. Testing on Different Bands:

   • Use the chart on the top case to select the corresponding band letter for testing (e.g., "B" for 80 meters).
   • Adjust the frequency and monitor SWR changes to optimize antenna performance.

8. Accuracy Check:

   • Compare the analyzer's results with a Vector Network Analyzer for accuracy verification.
   • Ensure that the analyzer provides reliable measurements for antenna testing and building.

9. User Feedback:

   • Share your experience with the analyzer in the comments section of the video.
   • Compare the performance of this analyzer with the MFJ version to assess differences and similarities.

10. Conclusion:

    • The compact battery-powered antenna analyzer offers a cost-effective solution for analyzing antennas from HF to UHF frequencies.
    • Stay tuned for more informative videos from Tech Minds and share your feedback on using the antenna analyzer.

By following these steps, you can effectively use the compact antenna analyzer for analyzing and optimizing your antenna systems across various frequency bands.
