Z-100 Low Cost Autotuner

The Z-100 is the definitive low cost automatic antenna tuner! It has been designed from the ground up to provide the power handling you asked for, in a small, lightweight package that is perfect for portable as well as sitting on your desk in your shack!

The Z-100 will tune with 0.1 to 125 watts (50 watts on 6 meters), making it an excellent choice for almost any radio or operating style. Backpackers and QRP operators will appreciate the latching relays. Power can be removed from the tuner once you have tuned. Additionally, when the tuner is not tuning, it draws nearly zero amps.

Additionally, the Z-100 features 200 fast memories which will decrease tuning time up to 95%!

This automatic antenna tuner will interface to many radios for added convenience. Our optional interfaces integrate the tuner to the radio so you can take advantage of radio faceplate "tune buttons" (if so equipped) or tuner signaled tuning. Please consult your radio manual for details on using it with an automatic antenna tuner. Interfaces are available for certain Icom, Alinco, Yaesu, and Kenwood radios.

Simple operation is the key to the Z-100. Provide a continuous carrier, then press and hold the tune button for 1 second. The Z-100 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.

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.

Please compare the price of the Z-100 to other brand auto and manual tuners... enough said!

LDG Electronics endorses the Z-100 Ultra from W4RT Electronics (http://www.w4rt.com/). The Ultra includes an internal battery pack (with batteries) and circuit modification that allows you to operate theZ-100 Ultra without needing to connect an external power source (but you still can). Nominally, over 10,000 full-tunes and many times more memory tunes before needing to change the long-life batteries. Itís outstanding for portable operations where power, weight, and space are issues!
