Z-100 Automatic Antenna Tuner - LDG Electronics
(e.g., ladder line), an external balun is required. The LDG RBA-1:1 balun will work with short random wires and the RBA-1 4:1 balun is suited for longer wires. Connect the HF antenna jack on your transmitter or transceiver to the Transmitter jack on the back of your Z-100 tuner using a coax jumper with standard PL-259 plugs.
