This tuner would tune a bucket of salt water!  Time owned: more than 12 months
I bought this ATR 20 tuner year ago when I got my ALS 600 amp. It wasn't cheap but it is worth every penny. The roller inductor is smooth and I have every tune position for my CW frequencies on a sticky note taped to my desk for quick reference. I quickly adjust the transmitter, antenna and the inductance to the sweet spot and I'm ready to go. The power and SWR meter is easy to read. This is a heavy, solidly built tuner which will be the last one I will ever need.

Great VSWR   Time owned: 0 to 3 months
Got the ATR-20 back after having Ameritron replace the roller inductor within the first few weeks. They recalibrated it also. I bought the ATR-20 to go with the Ameritron AL-811. Now it tunes the IMAX 2000 10-20 Meters. Prior to being fixed it only tuned the IMAX on 10 and 12 Meters. Smooth and properly working. It's great on the Cushcraft R7 and other Band specific antennas.
The IMAX may not be most "efficient" on 20 Meters but I do have many USA and DX contacts using it with the LDG IT-100 Auto Tuner.
Now with the ATR-20 I should be able to tune more effectively, even "Coat Hangers" Hi, hi. The Peak Hold is accurate. The Power is accurate. I like this tuner. I can see exactly what my reflected power is and my VSWR. Nice less than 1.5:1 with almost no to 1.5 watts reflected. With a tuner you may fine tune and broadband your antennas.
I do recommend this tuner.

SMOOTH  Time owned: 0 to 3 months
Had my tuner for 3 weeks now. Smooth and easy. What a differance from the MFJ I owned. Worth every penny. Tuned up a a few of my wire antennas with ease.

Great Tuner  Time owned: more than 12 months
I bought my ATR-20 about two years ago. I use it with my Icom IC-746PRO and my IC-745,and my AL-811H AMP ususlly at 600 TO 700 watts. It tunes Inverted V, G5RV,and homemade Dipoles with ladder line feed no problem. I have never had any trouble with the tuner at all, I think it will tune any antenna. 73 Bob,K7PSA

Great Product  Time owned: more than 12 months
I've had my ATR-20 for about 3 years now and have used it on a wide variety of antennas with power (on the meter) up to 900+ watts and have been totally satisfied. I love the quality of construction (no problems as others have posted) and the true peak power feature on the meter is very helpful.

A bit pricey but a fine product.

Pricey, but works well  Time owned: more than 12 months
I use it with dipoles hanging in trees, my tuner in my IC-746 couldn't handle them. I find the sweet spot and then activate the Icom tuner if the swr is a little high. If you can't tune it with the ATR-20 it can't be tuned.

GREAT!  Time owned: 0 to 3 months

I'm not sure why an ATR-20 review hasn't been written in 2 years. This is a fantastic tuner. For those of you who have difficulties with MFJ equipment, don't equate Ameritron with MFJ.

Purchased new, the tuner is solid and the power/SWR meter reads the same as the power setting on my TS-480S. I set 30W, I read 30W into a 50 ohm dummy. I set 100W, I read 100W into a 50 ohm dummy. At that relative level, it's repeatably accurate.

The built-in antenna switch with either direct, feedthrough or tuner-coupled output is another bonus. The finest feature is the continuosly tunable roller inductor for exciter powers <30W. I'm finding sweet spots I never had with my older tuner's 12-position inductor, and with increased tuner efficencies (max capacitance/minimum inductance). And the setting are extremely repeatable over all bands.

It's a hunk of change (~$430), but worth it.

Great Tuner  Time owned: 6 to 12 months
I am very happy with this unit.
I bought this tuner to go with my AL-811 and it has worked great, and I have had no problems with it. So much better then my MFJ. I use it with a 246' dipole and it tunes just fine on all bands. Now if they could make an Auto-tuner this reliable.

Excellent tuner  Time owned: more than 12 months
I own two of these (one in the primary station, one in the secondary) and I love it. I noticed the shaft coupler looseness in one of them and I have to adjust this, but other than that, it's a great piece of equipment.

Works Great!  Time owned: 0 to 3 months
I use mine on a sloper and it works great. I can go back to various frequencies and the variable Capacitor[s]and Inductor settings are right on every time. As I understand it, the shaft coupler set screws have been replaced with Allen screws that are supposed to bite into the shaft[s]and correct the problem of the shaft coming out in your hand. I don't think it has the fit/finish/quality that my Palstar AT-1500CV had but it does a good job.
