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.

The End Fed Half Wave Antenna - gnarc.org

If fed off center, say at 30%-70% point, impedance is approximately 200 ohms and can be used on multiple bands with an antenna tuner. Works with a 4:1 UNUN. See this link for more info. 4:1 impedance ratio is 2:1 turns ratio. If fed at the end (a.k.a EFHW), antenna impedance is in the 2000-4000 ohms range.
