Choosing antenna tuners & SWR meters comes down to a practical trade-off: do you need an automatic HF type, a roller tuner, built-in readings, portable operation, or a particular connection and compatibility label? These four used options cover distinct setups, so the product title and attributes matter as much as the price.
Quick take
Treat this as four different decision paths rather than one price list. Start with the capability named in your setup: automatic HF tuning, roller tuning, explicit SWR or power metering, portable operation, or desktop coaxial connectivity. The comparison below separates those use cases before the product notes add the important limitations.
Listed-price comparison
The listed prices run from $74.99 to $260, with a $185.01 spread between the lowest and highest entries. The bars show their relative position within this comparison, not performance or quality.
| Product | Listed price | Price bar |
|---|---|---|
| MFJ-900 Econo HF Antenna Tuner Ham Radio | $74.99 | |
| B&W VS300A HF Antenna Tuner | $99.00 | |
| Trio Kenwood AT 230 HF Antenna Tuner | $189.99 | |
| MFJ-986 HF Antenna Tuner 3KW Roller Tuner | $260.00 |
Decision matrix
- Automatic HF type: MFJ-900 is identified as HF and Automatic.
- Roller-tuner design: MFJ-986 uses the title phrase
3KW Roller Tunerand lists Universal compatibility. - SWR and power readings: B&W names an SWR Power Meter, while the Trio Kenwood attributes list both SWR Meter and Power Meter.
- Portable operation: B&W's description specifically identifies portable operation.
- Desktop and coaxial connection: Trio Kenwood lists Desktop form factor and Coaxial (SO-239) connectivity.
- Band wording: B&W specifies 1.8-30 MHz; MFJ-900 and Trio Kenwood are identified as HF, with the Trio Kenwood title also showing 1.8MHz and 29.7MHz.
- Power wording: MFJ-986 says 3KW, B&W says 300 Watts, and Trio Kenwood says 200W. Treat those as the figures to match against your equipment requirements, not as a simple ranking.
Product notes
MFJ-986 HF Antenna Tuner 3KW Roller Tuner
The MFJ-986 is the choice when the phrase 3KW Roller Tuner matches your setup. Its title and description identify a 3KW capacity and a roller dial for precise tuning, while its compatibility attribute says Universal. That gives it a distinct role among these four choices. The limitation is its Used condition, which is a concrete consideration for a shopper comparing product condition. Choose it when roller tuning and the stated 3KW figure are central to the decision; otherwise, the automatic or metered designs may align more closely with the intended setup.
MFJ-900 Econo HF Antenna Tuner Ham Radio
MFJ-900 stands out for its listed $74.99 price and straightforward identity as an HF antenna tuner with an Automatic type. That makes it the clearest starting point for a shopper seeking the automatic HF designation without moving into the roller-tuner wording used by MFJ-986. Its limitation is the format distinction: the product is identified as Automatic, while MFJ-986 is explicitly a roller tuner. Keep the decision tied to that stated type rather than assuming the two provide the same tuning approach. The Used condition is also part of the product description, so it belongs in the final comparison.
B&W VS300A HF Antenna Tuner 1.8-30 MHz w/SWR Power Meter Nice 300 Watts
B&W VS300A is the clearest match for a shopper who wants one tuner with explicit SWR and power readings. Its title names an SWR Power Meter, and the description adds a built-in SWR and power meter. The 1.8-30 MHz coverage and portable-operation description further define its use case. The limitation is the stated 300-watt figure, a raw power specification that should be matched to the radio setup rather than treated as interchangeable with every other number here. At $99.00, it is $24.01 above MFJ-900, while its meter wording adds a specific selection reason.
Trio Kenwood AT 230 HF Antenna Tuner 1.8MHz 29.7MHz 200W Tested Working Japan
The Trio Kenwood AT 230 suits a shopper who wants a desktop HF tuner with explicit SWR and power meters, coaxial (SO-239) connectivity, and a compatibility label that says For Kenwood. Its title includes 1.8MHz and 29.7MHz plus 200W, giving the choice clearly stated operating labels to compare with a radio setup. The limitation is that compatibility label: it says For Kenwood rather than Universal, so select it for that stated fit instead of assuming broad compatibility. Its Used condition is also identified, making the product a targeted choice for desktop metering and connection requirements.
Final recommendation by use case
- For the lowest listed price: MFJ-900, with its $74.99 entry and Automatic HF designation.
- For a roller-tuner requirement: MFJ-986, whose title explicitly names the
3KW Roller Tunerformat and Universal compatibility. - For portable SWR and power metering: B&W VS300A, based on its meter wording, 1.8-30 MHz label, and portable-operation description.
- For desktop metering with a Kenwood-labeled setup: Trio Kenwood AT 230, which lists SWR Meter, Power Meter, Desktop, and Coaxial (SO-239) attributes.
Match the selected tuner to the exact band, power figure, and connection label your station requires. The $185.01 spread makes that use-case match more useful than choosing by price alone.
