By the way, Wayne...

Are you aware of a companion Excel application for EZNEC called
AutoEZ? You can run many test cases in a few seconds using it. You can
find it on the EZNEC site.

It is how I generated the data I posted.

Thanks, I'll look for that. I run the old wood burning version 3.0.


BTW, Wayne, what are the dimensions of your metal roof? And how high?

It's about 20 by 35 feet, 9 feet above ground. it's a big patio cover.

The underside is relatively smooth, but the top has all the ribbed sections.
Ribs are about 20 feet long and separated by about 2 feet.

Also on top are various runs of conduit and three large rectangular covers
for the underside lights.

I know this is TMI, but I'm just illustrating why I haven't tried to model
the entire metal roof....it's complicated

And I don't really need accurate patterns.
