I have a Zero-Five 43 ft. verttcal and a K2. I use the KAT-2 built-in tuner with it. It tunes on all bands 80 through 10 meters with no difficulty. I don't have the 160 board in the K2 so can't comment on 160 with this tuner. I have about 50 radials, most 43 ft long and a little over 150 ft of Bury-Flex coax. This antenna would not tune well on 80 and didn't tune on 160 at all with an LDG AT100Pro auto- tuner. With a Palstar tuner I can tune 160 easily with this antenna. I suspect that the K2 tuner would be OK on 160 also.
As for the antenna, it's built like a tank. It's very easy to assemble and works well for me chasing DX on 40 and 80. If you have questions, you can speak directly with Tom the owner, just like dealing with Elecraft. A lot of guys speak negatively about this antenna design and show all the reasons it shouldn't work. All I can say is it works for me.
