The MFJ-812B VHF SWR/Wattmeter is built to withstand the rigors of amateur radio operation. It features a rugged, weather-resistant enclosure and is powered by a 9V battery, so you can take it with you to the field or use it in your shack.

1. Basic Features: Compared to more advanced models, the MFJ-812B has fewer features, such as frequency memory or data logging.

2. Battery Operation: While it can be powered by an external 12V DC power source, it does not have an integrated rechargeable battery, which may be a disadvantage for portable use.

3. Display Size: The display is relatively small, which can make it difficult to read under bright sunlight or at a distance.

Conclusion:

The MFJ-812B VHF SWR/Wattmeter is a solid choice for amateur radio operators who require a basic yet functional SWR/Wattmeter for their 144-220 MHz VHF operations.
