- Note: The antenna tuner can operate at 50MHz, but its optimal tuning range is between 1.8-30MHz. As the frequency increases, its impedance matching range will correspondingly narrow. When the antenna itself has a high standing wave ratio (SWR), the tuner may not be able to tune below 1.5 and might only tune to a slightly lower value. Additionally, it is recommended to maintain the radio's output power within the 6-12W range while the tuner is working, to support the tuning process
