Simple operation is the key to the Z-100Plus. Provide a continuous carrier, then press and hold the tune button for 1 second. The Z-100Plus tunes. The red LED indicates tuner activity and the green LED indicates an SWR of 1.0 to 1.5 (steady green LED) and 1.5 to 2.0 (blinking green LED). If your antenna is already resonant, place the tuner in bypass. Pressing and releasing the tune button quickly will bypass the tuner, taking all tuning components out of line. The operating range is 1.8 to 54 MHz and will tune a 10:1 SWR (3:1 on 6 meters) down to 1.5:1 or less. It will tune almost any coax fed antenna including dipoles, beams, and verticals. Add any 4:1 Balun to use ladder line or to tune long wire or Zepp antennas. This tuner carries a two year manufacturer's limited warranty. Radio cables are not included (see below).
