works well complete remote  Time owned: more than 12 months
My approach to antenna tuners is always put them as close to the antenna as possible. A tuner in the radio or amp is only useful if you expect to ever connect it directly to the antenna without a feedline. Since I don't ever run more than 100W I decided to use the Z11-Pro as the basis for a rugged remote tuner for use around the home that I could leave outdoors with the antennas.

I live in the desert SW so I was concerned about heat. I contacted LDG and they assured me the unit will be fine with ambient temperatures up to 140F. I put mine in a polycarbonate box covered with aluminum tape to help reflect some of the hot sun. In the box I put the LDG along with an MFJ 4116 Bias Tee and Elecraft BL2 balun kit. Antenna connections come out to two 5-way binding posts. Before closing it up I set it to Auto mode by pressing Func then tapping C Up until the inner two (of the four) LEDs are lit.

Then with another bias tee at the shack end, this gives me a maintenance-free fully automatic remote tuner located at the antenna connected back to the radio with any amount of coax. I've used it with long wires, inverted-Ls, ground planes and dipoles. Any time I QSY or change bands I give a quick tune with 1 Watt and watch the SWR drop within a few seconds. On the rare occasions when it can not find a match, it leaves the SWR at 10:1 so it is always clear one way or the other. I've had this setup for over two years, outside from freezing to over 110 F without any problems whatsoever.

I am very satisfied with the the LDG Z-11Pro.

Convienance for old guy  Time owned: more than 12 months
The magic smoke that makes this work has never left the box.

Why did I purchase this expensive accessory instead of properly tuning my antenna(s)? Only because I no longer enjoy putting up and taking down all those improperly tuned antennas for the freq I want to be on, and have always found eliminating SWR across multiple bands with "manual" units bit tedious.

Sure, it hunts and pecks to get there, but it often does! I have used it with several radios, including QRP, with very good results. I am currently using it with a 20-15-10 inverted V and a TS480AT. It often tunes better than the 480 (sometimes tunes when the 480 will not.) YMMV. And of course it can be tuned manually for SWL.

A couple of suggestions: Get your antenna as close as you can and ALWAYS tune with low power.

I give it a "good" instead of a "great" because recently, sometimes, it seems one or more of the relays becomes stuck. I unplug the unit, power up, and manual jog the relays. Also, it seems multiple memories are at work on the same frequency. Several momentary "Tunes" are needed to get the right one.

All things considered I am very happy I spent the money for this Z-11ProII.

No problems at all  Time owned: more than 12 months
Got this when I moved several year ago. It was early winter and no time for putting up a decent antenna. So dropped a 33 ft wire out the window (upstairs shack) to tree and ran it with my FT-817, using the free balun they included. Used only the internal batteries. Works like a champ. Got a good match on 40 through 10 and made a lot of contacts with it. Yeah I had a manual tuner but changing bands took only seconds. Have been happy with. Not one problem. Recommended.

Meh  Time owned: 0 to 3 months
This review is for the Z-11Pro II- It does alot of chattering sometimes after it's supposed to have memorized "The lowest match." The best match on some bands is ~1.5:1...a few jabs at the inductor/cap buttons brings it down to close to 1:1. For an auto tuner, I do a lot of button jabbing. I think this will be relegated to portable use with the FT-857 as its foot print is very small. I'll go back to my MFJ manual tuner for the home base. Oh, and the LED codes are very crpytic and blink their codes way too fast as mentioned in some other reviews.

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.

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.
