Well NB your right. Looks like wavrider was right on point. I didn't know what to expect, and I've never though about the point he made either. Shows me that somebody is thinking.

I sure didn't expect to see the phase shift that resulted. As generally happens with my models...I just put the dimensions in. I don't know enough to be tricky yet, but I pretty much suspect when a guy is not shooten' straight...regarding his modeling ideas.

The currents report is pretty revealing as to what happens though. I learned something again. This report is a very good demonstration of what happens with phasing...and these models very simply reveal that idea if one pays attention to the details.

Frankly I wondered what actually caused the reflector to attenuate the signals. I use to think it was like some kind of blocking deal going on, but now I can see why...it is the phasing that does it.

I kind of thought somebody would comment on the four monopoles idea I did at first, but I guess that didn't stimulate any curiousity, or understanding.

Phasing, what a headache! Four square antennas, ground mounted vertical forced current fed lacking in phase by 90 degrees and 118 degrees. Whole nother ball game there.

Google four square antennas then sit back, start reading and scratching your head.

It is fun to read though and took me a while to finally figure it all out and build one. Well lets be honest I think I got it figured out, use a Kw on 40 meters into that four square I was making come contacts. :thumbup1:

I think RickC has also done some phasing work on antennas.
