Feature:1. Using PIC18F2520 MCU and 7 groups of LC combination, high quality aluminum alloy material can make sure the durability and stability of the product2. Adopt HF32/10A and HF33/5A relay, the great workmanship can provide stable performance3. Using 3KV, high voltage ceramic capacitor, the frequency is 1.9-54MHz for great signal transmission4. With 8pcs T682 magnetic ring inductors design, heat generation is smaller than the original version5. Professional design and reasonable structure, convenient to replace and installSpecification:Item Type: Antenna TunerMaterial: Aluminum alloyMaximal: SSB120w, it is recommended to use it for a long time not larger than (SSB, 100w, FT8, CW, FM60W).Frequency: 1.9-54MHz (specifically affected by the length of the antenna and the degree of deviation of the standing wave).Tuning Impedance Range: 5-1.0K.Package List:1 x Antenna Tuner1 x Connection Line1 x PlugNote:Be sure to confirm that the cable is connected according to the mark, otherwise the product will be burnt out
