HT100 / HT110 is an RF adapter integrating aviation band frequency conversion and high-impedance antenna matching. It downconverts the 118MHz–138MHz aviation communication band to shortwave frequencies, allowing ordinary radios or SDR devices to easily receive aviation signals. It also features high-impedance conversion, with a three-position toggle switch on the top that freely switches between mixer mode, high-impedance mode and off state, paired with intuitive LED indicators, greatly facilitating multi-scenario signal reception for radio enthusiasts. Widely used by radio enthusiasts to receive 118-138MHz aviation band communications using ordinary radios or SDR devices (such as Malachite). It can also perfectly match high-impedance antennas such as magnetic rod antennas, passive small loop antennas or whip antennas to receivers or handheld transceivers with standard 50Ω input, effectively improving weak signal reception, making it a practical tool for outdoor exploration, aviation frequency monitoring and RF laboratory testing.
