LDG Z-11 Pro Auto Antenna Tuner USED | 12 Months Warranty

 

LDG-Z-11Pro Antenna-tuner. The return of a ledgend. The original portable Z-11 was one of LDG’s most popular tuners, accompanying adventurous hams to their backyards, or to the ends of the earth. Now meet the Z-11Pro, everything you always wanted in a small, portable tuner designed from the ground up for battery operation. Only 5″ x 7.7″ x 1.5″, and weighing only 1.5 pounds, it handles 0.1 to 125 watts, making it ideal for both QRP and standard 100 watt transceivers from 160 – 6 meters

The Z-11Pro uses LDG’s state-of-the-art processor-controlled Switched-L tuning network. It will match dipoles, verticals, inverted-Vs or virtually any coax-fed antenna. With an optional LDG balun, it will also match longwires or antennas fed with ladder-line

The Z-11Pro has 8,000 memories in LDG’s exclusive “3-D Memory” array, automatically storing tuning configurations for each frequency and band as you use them, for each of four antennas on the single RF port. Frequency sensing circuitry lets the Z-11Pro “know” your operating band and frequency. Whenever you transmit on or near a frequency you’ve used before, the Z-11Pro retunes from memory almost instantly (even in SSB!). Memories are retained indefinitely

Rugged and easy-to-read LEDs indicate SWR and status
The Z-11Pro uses latching relays which retain the tuned configuration even when powered down; current draw when not tuning is effectively zero

For maximum flexability, the user has the choice of many battery options; internal or external. There are solder pads on the PC board for the user to install a battery pack (not included) that best suits their needs. You could use 6 AAs and get several years of operation. If weight is a factor (for back packing), then three Lithium AAs will last about a year. If you just need a few months, the Z-11Pro will operate fine off a single 9V battery

Control from the front panel is simple and straightforward; just press Tune while transmitting, and the Z-11Pro will begin a tuning cycle. The Z-11Pro will even tune while you talk on AM or SSB. Although not required, optional interfaces are available for most Icom, Kenwood, Yaesu and Alinco transceivers. With the interface, a single button-press transmits a carrier, executes a tuning cycle and returns the radio to its original power and mode

The Z-11Pro is waiting for your next portable adventure. Where will you go next… ?
