The LDG Antenna Tuners Seem To Do A Nice Job

AT-600 Pro II
  I have been doing some research on the LDG Antenna Tuners . The AT-600 Pro II automatic antenna tuner gets a 4.4 out of 5 rating on eham.net, which is not a bad rating. Although there were only nine reviews they were all good. I have heard that they can seem a bit noisy when they are going through the automatic tuning process. If you would like to see a video on the AT-600 Pro II Antenna Tuner check out this link http://www.youtube.com/watch?v=xPLxPb-Umxw . I myself run the MFJ 993b auto tuner and when it auto tunes it can make some noise, but it only lasts for a few moments. The LDG AT-600 Pro II seems to be the same way, so it is not a big problem. My advise would be to buy one of the LDG meters they sell depending on what radio you are going to use it with. It is capable of handling 600 watts on ssb, which is not that bad. I have heard some stations running 200 watts to 500 watts and they sound awesome. It all depends on what antenna you are using and how much it multiplies the signal. Below are some of the specifications on the LDG AT-600 Pro II.
  • 600 Watts SSB and CW, 250 watts on 6M. 250 watts PSK and digital. - Easy to read LED bar graph display for RF power, SWR and status
  • 4,000 memories for instantaneous band changing - Two position antenna switch with memories for each position
  • Tuning time: 0.5 to 6 seconds full tune, 0.1 second memory tune - Built in frequency counter for memory operation
  • Frequency coverage: 1.8 to 54.0 MHz. - Tunes 6 to 800 ohm loads (16 to 150 ohms on 6M)
  • Enclosure: 10.5D x 8.5W x 2.5H inches - Weight: 3 pounds - Includes DC power cable.
