Fantastic  Time owned: 0 to 3 months
Just bought my second Z11 pro II and used it remotely at the base of a S9 43foot vertical during the recent Lighthouse/Lightship weekend at Swallowtail Lighthouse at Grand Manan Island in the Bay of Fundy. Worked as advertised, and had no problems with it whatsoever. Had it mounted in a weather proof box,along with a 9 to 1 UNUN, and fed power to it with 8 AA alkaline batteries. Used it on all bands from 80M to 10M....Flawless all the way.

fantastic  Time owned: 6 to 12 months
I use a Carolina Window40 at 35 feet antenna. the LDG-z-11Pro tunes 40-6 meters in a flash. Hit the cw key or tune button on the radio and it clicks in a instant to 1:1 swr. A very good piece of gear for the ham shack. That is of course, on previously tuned memories. for a new freq usually less that 4 seconds has been my experience.

Need to have Nifty card  Time owned: 3 to 6 months
Got this for my first outboard auto tuner. Try to remember if you have it on manual or auto, and then be sure to watch lights, as they do their thing quickly. That's the only quick thing for me, half the time, as when I do a "new" frequency, it usually chatters for about 8-9 seconds, then finally stops with a 2 to 3:1 reading?? This is on a "store bought" 80-10 dipole. Same for homebrew 40m. Gonna re-read the manual again..and again...see if I missed something. May just use my manual Ten Tec inline.

VERY GOOD TUNER  Time owned: 6 to 12 months
Nice easy to use tuner...bought it because my SGC auto tuner need too much rf to get it into life when using my green radio PRC 320 CLANSMAN.....

Cheap Junk  Time owned: 0 to 3 months
Tuner just keeps on tuning even after manual tuning. Would not tune 11m antenna to 10m band, just keep making noise. I really can't understand why some of these company's claim to have a great product, but in actuality they sell garbage ie: LDG and MFJ. After I took it back for a refund I found a $35 Dentron JR Monitor on ebay, this thing will tune anything. I will never buy LDG again.

Excellent tuner!!  Time owned: 0 to 3 months
I purchased this tuner in combination with a S9 31' vertical antenna. I put a large waterproof electrical box at the base of the antenna and a 12 volt power supply. I then used the LDG 1:1 balun and connected the antenna to the tuner. This setup is working amazingly well in my antenna strict neighborhood! I currently can tune 6m-75m without a problem and have good signal reports on all bands. I cannot tune 160m yet but I have a 4:1 balun to try and I'm sure this will bring the 160 meter world into play. I drive all this with a Icom 746 Pro, I start with low power (20w) then after the tuner find the match increase to full power and always get below a 1.5 to 1. It does take the tuner a few seconds to find a new match but stored matches are restored instantly on transmit. Very happy with the combination and LDG was super about answering my questions before buying.

Great simple auto-tuner  Time owned: more than 12 months
I've operated this tuner with the FT-857D and FT-817ND portable and it has always worked flawlessly. I recently sent away for the upgrade IC (cheap upgrade!) and find that it tunes faster with a variety of portable verticals and dipoles. I just love this rugged, fast, quick autotuner !

OK but power limited  Time owned: 6 to 12 months
The tuner works as advertised but watch your power output!! I burnt up a toroid using 30 watts PSK on 80 meters with a homemade 43ft. veritcal. LDG was GREAT in repairing and sending back no charge..

Unfortunately I smoked it again on 17 meters digital....low power too..not as bad this time so I will keep it in case I ever go portoble with low power one day.

The advertised 125 watt power capability applies maybe for short duration cw and ssb, but for digi modes keep that power below 25 watts and you will be fine.

For me, I just finished a very robust homebrew T tuner and no problems at 100 watts.

Works very well inc. contesting calling CQ  Time owned: 6 to 12 months
Bought it primarily for portable contesting use for HF and 6M using my 100' inverted-vee wire antenna fed with 300 ohm twin lead, 1:1 choke balun and a short 8' length of coax. Solid auto-matches <1.5:1 each time after initially working my way up each band (80M thru 6M, including all WARC bands), on low power before QRO operating. I use car booster pack with 12V cigarette plugs for both my LDG Z-11 Pro II tuner and my Hamgadgets auto-keyer. Recently during FD, it stretched our club 80-40-20-15 fan/trapped dipole to full bandwidth across 80-6M FD bands (although I couldn't get it to match on 160M). Always grounded to radio and a ground rod of some kind. Works quite well, with minimal heat build-up, even when holding a contest frequency for 45-60 mins using full 100W -- works as advertised. I'm very happy with my purchase and got a free, promotional LDG balun to boot!

Pretty good but not for running  Time owned: more than 12 months
This tuner pretty much matches everything. Two things to look for.

1. It searches for match endlessly when the voltage is < 8.2 V. With built-in 6 AA batteries, this is half-full (or half empty). No low-battery warnings.

2. Works well in casual QSOs or S&P but easily overheats when running in a contest.
