Easy integration means plug-and-play operation; installation could not be simpler. The ATU-100RA tuner goes anywhere with an HF radio… desktop, portable, parks, islands, or tall summits.

The ATU-100RA 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 54 MHz.
