Introducing the Z-100A Automatic Tuner
The Z-100A 100-watt automatic HF antenna tuner is similar to other LDG tuners you may
already be familiar with; it is a precision instrument that will provide many years of quality
service.
What makes this tuner different is that it is specifically designed for modern 100 watt
transceivers. With ease-of-operation in mind, this tuner is powered directly by the interface
on the back of the radio; no need to worry about any additional power connections. Also, a
single push button switch is usually all that’s needed to complete the tuning process!
The Z-100A also features low power consumption since it uses latching relays which require
no power once it’s tuned.
Be sure to read the entire manual to ensure safe operation and long life of the Z-100A. With
proper care this tuner will provide many hours of enjoyable operation.

Connecting the Z-100A tuner
The Z-100A tuner is designed for indoor operation only; it is not weather proof / water
resistant. If you use it outdoors (Field Day, for example), ensure it is properly protected
from rain, dust, etc.
The Z-100A is designed for use with coax-fed antennas. If operating with long-wire or
ladder-line-fed antennas, an external balun is required. The LDG RBA-4:1 or RBA-1:1 is ideal,
depending on the antenna and transmission line used.
1. Make sure your radio is turned off.
2. Connect the HF/50 MHz antenna jack on the transceiver to the “RADIO” jack on
the Z-100A, using a 50Ω jumper.
3. Connect a 50Ω coax antenna feedline to the “ANT” jack on the Z-100A.
4. Connect one end of the supplied radio interface cable to the tuner port on the
back of your radio.
5. Connect the other end of the supplied radio interface cable to the “INTERFACE”
jack on the rear of the Z-100A.
6. Turn on the radio.
7. Select the desired operating frequency and mode.
8. Key and hold the radio in CW or FM mode, then press and release the TUNE
button on the front of the tuner.
9. The transceiver will transmit with a minimal amount of power as the Z-100A
begins. You may hear the relays chatter as the tuner searches for a match. At the
end of the tuning cycle, the SWR has been lowered.
10. You are now ready to operate!

Specifications & Ratings
To ensure proper operation and to avoid equipment failure, the following specifications and
ratings must be observed:
Frequency Range: 1.8 to 54 MHz
Maximum Input Power: 125W PEP (CW / SSB), 30W (Digital / RTTY/ FM)
Input Impedance: 50 Ω
Tuning Range: 10:1 SWR, 20uH, 1300pF.
Memories: 2000
Retune Time: < 1.0 sec.
Voltage: 13.8 VDC + 15%
Current Draw: 250 mA tuning, 20 mA idle
Size: 6.3”x6.3”x1.5” (160x160x40mm)
Weight: 1.5 lbs (680 g)
Mobile Operation
The Z-100A is also perfectly suited to mobile operation. It can be installed under the
dashboard along with the transceiver or mounted remotely. The only requirement is that
the tuner remain dry.
MARS/CAP Coverage
The Z-100A provides continuous coverage over its specified range; not just in the ham
bands. This makes it useful for MARS or CAP operation, or any other legal HF operation.
Important Safety Warning
Never install antennas or transmission lines over or near power lines. You can be seriously
injured or killed if any part of the antenna, support or transmission line touches a power
line. Always follow this antenna safety rule: the distance to the nearest power line should
be at least twice the length of the longest antenna, transmission line or support dimension.
Also be aware of and follow electrical and safety codes of your municipality.

OPERATION
To start a full tuning cycle press and hold the TUNE button on the front panel of the Z-100A
until the red STATUS LED lights up, and continue holding until the STATUS LED goes out. The
TUNE button can be released once the STATUS LED has gone out. A full tuning cycle will
begin.
Most of the time the Z-100A’s memory tuning will allow a good match to be found quickly if
transmitting on the same frequency as a previously stored match. Under certain
circumstances, especially when using a different antenna, the memory tuning will recall a
previous match which is acceptable, but isn’t the best match possible for this situation. In
this case, forcing a full tune will cause the Z-100A to seek a better match than the match
already stored in memory.
The SWR LED and STATUS LED are used to indicate both operating modes, tuning status,
and error codes.

Your Z-100A tuner
Front Panel
On the front panel there is one pushbutton and two LED indicator lights.
TUNE Button: Initiates either a memory tune or a full tune, and also toggles the tuner
between “active” and “bypass” modes.
SWR LED: Lights or blinks to indicate SWR condition.
STATUS LED: Lights to give feedback on button activation; lights during tuning; provides
tuning status at the end of a tuning cycle.

Rear Panel Connectors
The rear panel of the Z-100A features four connectors.
ANT: Connect the 50Ω coax antenna feedline to the standard SO-239 connector.
GND (wing nut): Connect to antenna system ground if needed.
RADIO: Connect the 50Ω coax jumper cable from this standard SO-239 connector to the
Antenna jack on the rear of the transceiver.
INTERFACE: This 6-pin mini-DIN connector connects to the radio interface cable. DC power
is also supplied via this connector. Be sure to turn off the transceiver before connecting or
removing cables.

Operating Hints
Transceiver Tuner Status Indication
Different models of ICOM transceivers indicate the status of the external tuner with slight
variation. Most will show a graphical or textual icon on the screen to indicate that the tuner
is active and has properly tuned. For example, the IC-7000 displays a blinking icon
while tuning, and a solid icon when tuning is complete. This icon disappears when
the tuner is bypassed, and blinks if a tuning cycle failed to find a good match. Other ICOM
transceivers behave similarly. Consult your transceiver operating manual’s external tuner
section for more information. When in doubt key the radio in AM and press the Tune button
on the LDG tuner.
