The MFJ-872 1.8-200 MHz SWR Meter is a versatile and reliable tool for any amateur radio enthusiast. This SWR meter is designed to cover a wide frequency range, making it suitable for a variety of applications. With a frequency range of 1.8 to 200 MHz, it can be used for HF, VHF, and UHF bands.
The MFJ-872 is a 5-20-200W power meter, meaning it can handle up to 200 watts of power. This makes it suitable for use with a wide range of transmitters, from low-power handheld radios to high-power HF transceivers. The meter features a large, easy-to-read digital display, which shows the SWR (Standing Wave Ratio) and power level in real-time.
The SWR reading is an important indicator of the efficiency of your antenna and transmission line. A low SWR reading indicates that the signal is being transmitted efficiently, while a high SWR reading indicates that there is a problem with the antenna or transmission line that is causing the signal to reflect back towards the transmitter. By using the MFJ-872 to monitor the SWR, you can identify and correct any problems before they cause damage to your equipment or reduce the effectiveness of your radio communications.
The MFJ-872 also features a built-in attenuator, which allows you to safely measure the power output of high-power transmitters. The attenuator reduces the power level to within the safe operating range of the meter, preventing damage to the meter and ensuring accurate readings.
The MFJ-872 is a compact and portable device, making it easy to take with you to the field or to different operating locations. It is powered by two AA batteries, which provide long battery life, and features a backlit display for easy use in low-light conditions.
Overall, the MFJ-872 1.8-200 MHz SWR Meter is a powerful and versatile tool for amateur radio operators. Its wide frequency range, high power handling capacity, and built-in attenuator make it suitable for a variety of applications, while its compact size and long battery life make it easy to use on the go. Whether you are a seasoned amateur radio operator or just starting out, the MFJ-872 is a valuable addition to your equipment list.

4. Affordable: Compared to some other SWR meters, the MFJ-872 is relatively affordable, making it an attractive option for budget-conscious ham radio operators.
Cons:1. Plastic construction: The meter is made of plastic, which may not be as durable as a metal construction.
2. No built-in antenna tuner: While the MFJ-872 can display SWR readings, it does not have a built-in antenna tuner to automatically adjust the antenna for optimal performance.
3. Limited features: Compared to more expensive meters, the MFJ-872 has fewer features, such as an RF power meter or a peak SWR memory function.
In conclusion, the MFJ-872 SWR Meter is a great option for ham radio operators looking for a budget-friendly, wide-range SWR meter with high power handling capabilities. However, if you require more advanced features such as an antenna tuner or RF power meter, you may want to consider a more expensive meter. Ultimately, the best choice depends on your specific needs and budget.
