AT-200PROII LDG Electronics Automatic Antenna Tuner 1.8-54 MHz, 5-250 Watts SSB and CW. 100 watts on 6M. 75 watts with PSK or Digital Modes. 2 Year Warranty

This does a great job at matching my antennas to the frequency I'm working. It's a little noisy when it's tuning but drops the SWRs nicely. I particularly like the ability to manually tweak the setting and store it.

My Yaesu FT-991A and Kenwood TS2000 both have built in tuners. This tuner provides a much better mach of my random wire, on the fly. I do alot of FT8. When I switch bands the tuner automatically tunes/learns the band. You can also fine tuner the band manually and store it. The tuner remembers it. With the internal tuners I could not tune 60 &160m. 80 & 40m had hard time tuning... not with this tuner. It tunes my random wire on 6-160m with no issues once it learns the band.

A little noisy until it settles but the memory is good and within reason it loads almost anything.

This little antenna tuner replaces my old TenTec manual tuner that decided not to work any longer. I guess I didn't know what I was missing all these years with a automatic tuner versus the old school method that I had with the TenTec. Although the TenTec will survive many more output watts from larger transceivers, this little bugger will take 200watts continuous which ain't bad. My only complaint is the manual is not the easiest to understand when a unit like this has multiple process buttons to operate it. I resorted to LDG's YouTube channel to fill in the details which they did quite well. The unit can be used with two radio's via a direct link, one Yuasu and one Icom. But only those two and no others. As described in the title it is automatic and tunes when it senses a carrier wave. You will either have to whistle or talk for it to tune or you can use a More key or paddle or switch the mode to FM or AM in order to send the signal. Either way, it only takes, at the most, two seconds to tune a difficult antenna. Ideally, most trip-banders will not need a tuner, but if you have to tune a WARC band using the trip-bander, you will most likely need a tuner. The tuner is also good for wire antenna's either a G5RV or a Windom or a stealth wire with a balun. It runs off of 12vDC so will operate off of a car battery so can be used mobile which is good for those rascally whips. For the money and the size, I don't know how I got along without the LDG AT-2000PRO all these years.

I needed a wider range tuner to match my IC 775 DSP to some antennas that were out of range of the 3:1built in tuner. This one does the job quickly and with little fuss. It hasn't failed on any reasonable attempt. I set by accident my 10 meter vertical while on 40 missing the Vertical it failed to match but it had to be extremely out of range my fault not the tuners. I caught it and was turned up and on the right antenna and 1:1.5 to one in under a second. It beats my old manual Versa Tuner in speed when you choose the right antenna hands down.

This little box is really really good at matching my crappy antennas. I was using a manual one and bar none, the LDG is not only faster(Dah...) but was able to match antennas that I never could. I would highly recommend it.

Be cautious. I returned a defective item and ordered a replacement and was charged a15% restocking fee which I believe is unreasonable because the item was clearly defective. It failed to operated properly after 3 days. the replacement item is perfect.

The internal ATU on my IC-7300 wouldn't tune my vertical on 40 meters. The AT-200 integrates well with the 7300 and tunes both my end-fed wire and my vertical with no problems. Highly recommended.
