Boost Performance with Our HF Antenna Tuner
Ensure maximum power transfer and protect your transceiver with our high-quality HF antenna tuner. Designed to match your antenna system to a 50-ohm load, it improves signal strength, reduces SWR, and gives you the flexibility to use a wide range of antennas—even non-resonant ones. Perfect for reliable, high-efficiency HF communication.
About this Antenna Tuner Unit
This ATU can generally tune an SWR of 3:1 or better and requires 10 watts to 30 watts to tune.
The maximum power used during tuning should not exceed 30 watts during tuning. (it can be set to 100 watts after tuning, and work at this power, otherwise the components and board can be burnt – this does not fall under the warranty)
The tuner will tune from 1.8 Mhz to 54 Mhz
