Description

The ATU-500 contains a set of 7 switched inductances with an uneven pitch, from 0.05 μH to 4.5 μH, and a set of 7 capacitors with uneven pitch, from 10 pF to 1 nF.  This allows the ATU to work effectively in a wide frequency band, overlapping radio amateur HF ranges from 1.8 to 50 MHz.   The used toroids are T130-2EW with low loss and low-temperature rise. All high-voltage NPO capacitors have 4kV withstand voltage.
