Got the new antenna working yesterday. There were a few problems with the cables to sort out but that only took a short time. Then there were several repetitions of RTFM before I finally figured out how to configure the control box.
Turns out that I had to enable the option for 80M in order for any band to work. The instruction book did not even hint at this. SteppIR needs some help writing their manuals.
Once it was all working I made contact with stations in Greece and Italy. Not major DX but pretty good for early afternoon. At least it proves the antenna is working. I’ll be playing with it some more today and get a better feeling for its performance.
