Quick take
Choosing antenna tuners & SWR meters means balancing four practical questions: Do you need battery charging for outdoor use, a built-in meter at the lowest listed price, a Kenwood-oriented desktop unit, or roller tuning for a higher-power setup? These four HF tuners take noticeably different approaches, so the right pick depends more on your station than on price alone.
The listed-price spread is $161, from the B&W VS300A at the low end to the MFJ-986 at the high end. AT-100M is the only new unit in the group, while the B&W, Trio Kenwood, and MFJ products are marked used.
Listed-price comparison

Decision matrix
- Battery charging and outdoor-oriented use: AT-100M, with its built-in lithium battery and Type-C charging.
- Lowest listed price with metering: B\&W VS300A, whose title and description identify an SWR and power meter.
- Kenwood-centered desktop setup: Trio Kenwood AT 230, with For Kenwood compatibility, desktop form factor, and coaxial SO-239 connectivity.
- Roller control and a 3KW title specification: MFJ-986, whose description highlights a roller dial for precise tuning.
Product notes
AT-100M Universal HF Antenna Tuner
At $141.98, the AT-100M combines a 1.8-30 MHz range with a 100W title rating, an SWR power meter, a 3300mAh lithium battery, and Type-C charging. That mix makes it a sensible match for an operator who wants battery-supported outdoor sessions and compatibility with multiple modes, including SSB, CW, AM, FM, and FT8. Its limitation is the stated power envelope: the description lists a 120W instantaneous SSB peak and says FT8 transmit power should not exceed 50W. Choose it for charging flexibility and versatile HF use, rather than for a station built around the 3KW specification found in the MFJ-986 title.
B\&W VS300A HF Antenna Tuner
At $99, the B\&W VS300A is the least expensive listed choice and pairs a 1.8-30 MHz band with a built-in SWR and power meter. Its title specifies 300 watts, and the description calls it suitable for portable operation. That gives shoppers who want a meter-equipped HF tuner a concrete starting point at the bottom of the $161 price spread. The limitation is its used condition, which sets it apart from the new AT-100M. Its title and description emphasize the meter, 300 watts, and portable operation, while the AT-100M explicitly adds battery and Type-C charging. Choose the VS300A when those first three characteristics matter most.
Trio Kenwood AT 230
The Trio Kenwood AT 230 costs $189.99 and is identified as a used HF tuner with a 1.8-29.7 MHz range, 200W title rating, SWR meter, and power meter. Its attributes also specify For Kenwood compatibility, coaxial SO-239 connectivity, and a desktop form factor. The title identifies it as Tested Working, giving it a specific appeal for a Kenwood-centered station where those connection and metering details fit the setup. The trade-off is that its compatibility wording is For Kenwood rather than Universal, and its listed upper frequency is 29.7 MHz. This is the focused choice when the Kenwood pairing matters more than broad compatibility wording.
MFJ-986 HF Antenna Tuner
The MFJ-986 is priced at $260, and its title names a 3KW roller tuner. The description says its roller dial allows precise tuning, while the attributes identify Universal compatibility and a used condition. That combination makes it the direct candidate for a setup where roller control and the 3KW title specification are central requirements. The limitation is both the $161 gap above the B\&W VS300A and the used condition. Its title emphasizes the tuner and roller design rather than the SWR/power-meter wording used for the AT-100M, B\&W, and Trio Kenwood units. Choose the MFJ-986 for roller-tuner control, not simply because its power number is larger.
Final recommendation by use case
For battery-supported outdoor operation, choose the AT-100M Universal HF Antenna Tuner. For the lowest listed price paired with a 300-watt title rating and built-in metering, the B\&W VS300A is the most direct match. A Kenwood-focused desktop station points toward the Trio Kenwood AT 230, especially with its SO-239 connectivity and named meters. If roller control and the 3KW title specification drive the decision, choose the MFJ-986. The central trade-off is straightforward: portability, a lower-priced used meter-equipped unit, Kenwood-specific fit, and roller tuning each lead to a different tuner.
