LDG Electronics endorses the Z-100 Ultra from W4RT Electronics (www.w4rt.com).
The Ultra includes an internal battery pack (with batteries) and circuit modification that allows you to operate the Z-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. It’s outstanding for portable operations where power, weight, and space are issues!
The Z-100 is the first 0.1 to 125 watt automatic antenna tuner for under £150. Power consumption is ZERO amps when not tuning, making it perfect for portable operation with batteries.
The small footprint is ideal for today's small 100-watt or QRP radios. The tuner uses LDG's standard high efficiency, microprocessor controlled, switched "L" network to work with Dipoles, Verticals, Inverted Vees and other coax fed antennas. Use the RBA-1 external balun for long wires or ladder line fed antennas. Optional interface cables provide DC power and control from most Icom, Alinco, Kenwood and Yaesu radios.
Specifications:
ZERO current draw when not tuning: latching relays hold tune forever.
0.1 to 125 watt power range.
Status LEDs for SWR and tuning state.
Tuning time: 0.5 to 6 seconds, 3 seconds average.
Optional interfaces for Icom, Alinco, Kenwood and Yaesu available.
Power requirements: 9 to 16 volts DC at 300 mA Max.
Microprocessor controlled, easily upgradeable.
1.8 to 54.0 mHz coverage. Tunes 6 to 800 ohm loads (10 to 1 SWR)
For Dipoles, Verticals, Vees, Beams or and Coax Fed Antenna
Optional external Balun allows tuning of random length, long wire or ladder line fed antennas
Small Size Enclosure: 14.0 x 13.5 x 3.8 cm . Weight: 400g.
