Page 5 getting to know your z-100plus your z-100plus is a quality, precision instrument that will give you many years of outstanding service; take a few minutes to get to know it. Tuning is performed when the tune button is pushed on the front of the z-100plus and held for one second. The tuner can ...

Page 6 rear panel the rear panel of the z-100plus features five connectors. Antenna connector: connect the 50-ohm coax antenna feedline to this standard so-239 connector. Gnd connector (wing nut): connect to antenna system ground. Transmitter connector: connect a 50-ohm coax jumper cable from this s...

Page 7 installation the z-100plus tuner is designed for indoor operation only; it is not water resistant. If you use it outdoors (field day, for example), you must protect it from the rain. The z-100plus is designed for use with coax-fed antennas. If use with longwires or ladder-line-fed antennas is...

Page 8 operation basic tuning operation the z-100plus is operated from the front panel tune button on the z-100plus itself 2 . Two types of tuning cycles are available; a memory tuning cycle and a full tuning cycle. The memory tuning cycle attempts to tune quickly based on having previously tuned on...

Page 10 status indicators the swr led and tuning led are both used to indicate operating modes, tuning status, and error codes. The following table lists the led status codes and their meaning. Led indication meaning tuning led on. Tuner is tuning. Tuning led goes out, swr led comes on solid. Tuner ...

Page 11 mars/cap coverage the z-100plus provides continuous tuning 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. Optional internal battery installation the z-100plus is designed to allow the user to inst...

Page 13 circuit. At any given rf frequency, each of these can exhibit resistance, and impedance in the form of capacitive or inductive “reactance”. Transmitters, transmission lines, antennas, and impedance the output circuits of a transmitter, the transmission line, and the antenna, all have a chara...

Page 14 automates this process. No tuner will fix a bad antenna. If the antenna is far from resonance, the inefficiencies inherent in such operation are inescapable; it’s simple physics. Much of the transmitted power may be dissipated in the tuner as heat, never reaching the antenna at all. A tuner ...

Page 15 about half a second to run. A word about tuning etiquette be sure to use a vacant frequency when tuning. With today’s crowded ham bands, this is often difficult. However, causing interference to other hams should be avoided as much as possible. The z-100plus’s very short tuning cycle, as lit...
