"phase distortion"? I assume you mean the time delay differences and the general phase shift? Not some sort of narrow band dynamic effect. I addition the splitter circuits were not phase coherent If

Another notion that occurs to me is that with the Steppirs, you could detune some of the antennas at any given time. That *might* produce a situation where you could run, say, an 8-high close-spaced

It's really no different than tuning the elements on a single boom. The challenge, I've found, is setting up an appropriate goal function for the optimizer. This is not much different than the curren

I'm not understanding the need for the elevation rotation. Is he planning on using this array for HF EME, or is it to be used for some other purpose? 73 de Al, KE1FO -- Visit my amateur radio contest

So the Jansky array isn't going to hack it for top band. Google also turned up some SW broadcast curtain arrays with towers on train tracks, which are probably a bit larger (39 and 41m bands maybe).
