If you’ve been looking for a low-cost, easy-to-use antenna analyzer, the FG-01 might be exactly what you need. In this hands-on review, I walk through how it works, what it does well, and whether it deserves a place in your ham radio toolkit.
This is based on real-world use with a PAR EndFedz 20 antenna, where the FG-01 shows surprisingly solid performance for its price point.
First Impressions of the FG-01
The FG-01 immediately stands out for one reason: simplicity.
- Compact and portable
- Battery-powered (no external supply needed)
- Clean interface with minimal controls
- Designed for quick field use
This is not a lab-grade instrument—and that’s exactly the point. It’s built for practical antenna tuning without friction.

How the FG-01 Works (Real Usage)
The strength of this device is how quickly you can get meaningful data.
1. Frequency Adjustment
The top control allows you to change frequency up or down, and by pressing and holding, you can switch between digit precision.
This gives you two modes of operation:
- Fast scanning across bands
- Fine tuning specific frequencies (e.g., 100 kHz steps)
That dual control is extremely useful when dialing in an antenna.
2. Scan Width Control
The bottom setting (indicated by a red arrow on the display) controls the scan width.
- Wide scan → overview of band performance
- Narrow scan → zoom in on a specific frequency
This is essential when you’re trying to fine-tune resonance points.
3. SWR and Impedance Readings
The display provides two critical metrics:
- SWR (Standing Wave Ratio)
- Impedance (Ohms)
In your test setup:
- Frequency: ~14.2 MHz
- SWR: ~1.2:1
- Impedance: ~42 ohms
That’s a very solid match, especially for an HF antenna.
Why This Matters
- SWR close to 1:1 = efficient transmission
- Impedance near 50 ohms = optimal system performance
The FG-01 makes this instantly visible without complicated menus.

Real-World Test: PAR EndFedz 20 Antenna
The analyzer was tested on a PAR EndFedz 20, a popular portable HF antenna.
Observations
- Easy to locate resonance point
- Stable SWR readings
- Quick response when adjusting frequency
- No lag or confusing interface
This is exactly the type of use case where the FG-01 shines:
field tuning, portable setups, and quick diagnostics.
Who This Analyzer Is Best For
Ideal Users
- Ham operators who tinker with antennas regularly
- Portable / field operators
- Beginners who want a simple, no-nonsense tool
- Budget-conscious hobbyists
Less Ideal For
- Advanced users needing deep analysis or PC integration
- Lab-grade measurements or engineering work
FG-01 vs More Expensive Alternatives
Category | FG-01 | High-End Analyzer |
|---|---|---|
Price | Low (~$250) | $400–$800+ |
Ease of Use | Very high | Moderate |
Portability | Excellent | Good |
Features | Basic but effective | Advanced (graphs, memory, PC) |
Learning Curve | Minimal | Steeper |
Bottom line:
The FG-01 trades advanced features for speed, simplicity, and affordability—and that’s a smart trade for most operators.
Pros and Cons
Pros
- Extremely easy to use
- Fast frequency scanning and tuning
- Clear SWR and impedance readings
- Portable and battery-powered
- Strong value for the price
Cons
- Limited advanced features
- No data logging or PC connectivity
- Basic interface (by design)
Is the FG-01 Antenna Analyzer Worth It?
If your goal is to quickly tune antennas without overcomplicating things, the answer is yes.
This is especially true if you:
- Experiment with different antennas
- Operate portable or in the field
- Want reliable SWR readings without a steep learning curve
At around $250, it hits a very practical sweet spot.
Final Verdict
The FG-01 antenna analyzer is exactly what many ham radio operators have been waiting for:
A low-cost, easy-to-use, no-nonsense analyzer that gets the job done.
It’s not trying to compete with high-end lab equipment—and it doesn’t need to. For everyday antenna work, tuning, and experimentation, it delivers where it matters.
