AT-600PROII LDG Electronics Automatic Antenna Tuner 1.8-54 MHz, 600 Watts, 2 Year Warranty

I purchased this tuner to use with a 600 watt linear. It works very well and I also purchased the optional meter for it, which provides a very nice display for use while tuning the amp. The tuner takes everything the amp can dish out. Even though it's rated at 600 watts, I was told by LDG that it will handle close to 700 so that it will handle a 600 watt amp with ease. My only complaint is that mine arrived with a some scuffing on the top cover, which was strictly cosmetic. Amazon refunded some of my purchase price to compensate me for that but otherwise, the tuner has worked flawlessly. It's a very good tuner and the led displays are useful but I do recommend the optional meter which I don't think is sold by Amazon. I purchased mine through Amateur Electronics. It is much larger that the pictures, is LED backlit and provides a nice large and easy to read display. The meter comes with an S-video cable that plugs into the back of the tuner. The optional meter doesn't measure the RF directly, I really like this because there is no coax jumper needed so it's very flexible for placement and keeping the connections for RF to a minimum. The tuner will function just fine without the external/optional meter and you can use only the LEDs to help you tune the amp but the optional meter is much more detailed. All in all, I'm very satisfied with this purchase.

Great Tuner, Works well with no issues. I have it paired with the M-600 Meter. Easily handles my 600 watt Ameritron AL-811Gotta love one button tuning. Read the manual and do not tune with power.

HOWEVER, IT REQUIRED A BALUN FOR ONE MY ANTENNAS AND SINCE ALL MY ANTENNAS FUNCTION AS THEY SHOULD, I DIDNT FEEL IT NECESSARY CHANGING ANYTHING. OTHERWISE YOUR PRODUCT IS A SUPERB ITEM. NO PROBLEMS WHATSOEVER WITH IT OTHER THAN IT JUST WOULD NOT WORK WITHOUT A BALUN.. I HAVE RETURNED IT TODAY 04JAN2021. JUST WANTED YOU TO KNOW,, THANKS W8KJP

works great with meter for tuning my Kenwood.

So very easy to connect and use. I wish I bought the AT-600PROII a long time ago. Makes switching and operating operating on different bands so easy.

Bought mine hard as hell to figure out couldn't figure out why my radio was not getting out unhooked it used my radio's tuner and it put's out nothing but a boat anchor company took down their website be aware of this not good and this is not the first bad one I've worked with !

I wanted to replace my old MFJ manual tuner, so I emailed LDG and asked if the AT600 would tune my G5RV. The G5 is notoriously bad tempered toward tuners. I got a reply quickly from one of their engineers, who said it would be no problem. So I ordered the unit. However, when I set the LDG up, it just clicked away and never did the job. The two stars are for the ease with which I got a full refund when I sent it back to LDG. I went back to the MFJ and it still works fine, just more work to change bands.

Works Great!
