I gave this tuner a bad review I was able to get a copy of my receipt from HRO and got the tuner repaired and upgraded under warranty. I am impressed.

Great Value
|
Time owned: more than 12 months

I've used this little bugger on a Zero-Five 43 foot vertical and more recently on a trap dipole for 75/40... tunes fast, quietly (once it learns the freq) and the LED readouts make a "go-no go" decision for the freq easy. This is a great little tuner, easy to set up and use, and works fast,every time!

Roofspace Installation
|
Time owned: 0 to 3 months
|
I have limited space for an external antenna so installed an Alpha Delta DX-EE in roofspace
The DX-EE is 40ft long and my attic is 26ft long, so I bent the ends into a Z shape!
I then ran 30ft coax into an LDG Z-11 pro ATU in the shack.
I fired up on 5 watts and it tuned up perfectly across all bands from 80m to 6m!
I am glad I read the reviews of the Z-11 pro before, otherwise the clatter from the relays would have caused me some concern - but I knew what to expect!
I tried a contact on 20m and 5W power and made the trip from UK to Bulgaria - distance of 2500Km (1500 miles)
So I am very happy indeed with antenna and ATU
I can definitely recommend

Very happy with it
|
Time owned: 0 to 3 months

I have mine outside in a waterproof box with flashlight batteries for power. It feeds a center fed dipole with open wire line through a 4:1 balun. The dipole is a 1/2 wave on 80m and the tuner happily tunes it on all bands from 80 to 10.
I have coax from the box into the house which really gives me the best of both worlds. I get the convenience of coax to get outside which means no RF in the shack problems etc and then the efficiency of open wire.
Changing bands just needs a short burst of RF. My only wish would be to have a way to switch it out which would be useful for general listening throughout the HF spectrum. I'd be happy to run a control line out along with the coax but I don't think there is a way to switch it out even with the front panel buttons.

Works fine
|
Time owned: more than 12 months

I have two of these. Have had several other LDG tuners, from their original QRP tuner and Z11 to an AT-1000 (not yet yet installed).
At Field Day, I used a Z11-Pro on internal battery power to remotely tune a wire elevated by an RC helicopter. Set on automatic, it dealt with wire sometimes half on the ground, and sometimes with being pulled into the air and slammed down again. Still works!
I use one at home in series with a Balun and an RF transformer for trouble-free operation across the HF spectrum. I've learned it can't match everything, but it doesn't take much help to match everything I've thrown at it.

Does an excellent job

Time owned: 3 to 6 months

I have used the Z-11 Pro with my Icom 746 Pro and Yaesu 857D as a base tuner loading a Caroline Windom. It has performed very well with absolutely no problem keeping the SWR below 1.5 - 1.0. It has also performed very well in my mobile installation with hamsticks. It is very important for both base and mobile to provide a very good ground.

I got mine to use with my TS-520S Kenwood hybrid hooked up to a G5RV, inverted L, and 40M Delta loop. It worked great out of the box, then I put the battery pack on, and it started acting up and finally quit tuning. I sent it back to LDG and got it back in a couple of days. Tried it again, and it wouldn't work so I sent it back with some angry remarks. Found out I had shorted the battery pack when I installed it both times. I really felt stupid. Now that LDG corrected my error, it works perfectly. They have great customer service, the warranty is for two years which is great for idiots like myself. Read the directions, the battery pack is easy to install, but somehow I managed to screw it up. Great little tuner at an affordable price.

Home Run !

I have operated my FT-897D with this dynamic, little tuner for 3+ years and could not be more pleased. The antenna is an end-fed Zepp used in my limited space condo setting. This tuner does well across most bands with the FT-897D. Where as my FT-890 with built in tuner will not tune the Zepp as well. This unit is well constructed, fairly easy to use once directions are read and stacks well on top of my FT-897. Would purchase again.

doesn't bring the swr right down.
|
Time owned: 6 to 12 months

I found it to be quite impressive but when you ask the unit to bring the swr down to 1.5 or below it goes into tuning cycles in the middle of your overs: very annoying!Exasperating! Makes you want to throw the thing against the wall!

Didn`t work as advertised
|
Time owned: months
|
|
This thing didn`t work out of the box,The tuner would constantly try to retune everytime when I started transmitting.I tried everything in the book-and yes I did read the directions.I have a Alpha Delta ee and it would not tune on 40 meters which my manual MFJ tuner will.The relays would get stuck all the time and I would have to unplug it.Too bad-maybe I got a lemon after reading all the other decent reviews.So I returned the unit.
