OK, I'll try the 70* degree angle below horizon.

 

The 70' foot height idea that I thought you were talking about...showed similar trends as previously noted at 27' feet. The 72" horizontal radials made a .50 dbi gain advantage over the slanted down radials.

 

That's not much, but maybe this is why Solarcon uses the shorter radials, I just don't get why they have the GPK, with slanted down radials though. Maybe it looked better to the ad group.

 

With 72" radials slanted at 70* degrees the advantage seemed to start getting better again, with 5.37 @ 5* vs. 5.41 @ 5* degrees for the horizontal radials. So, this affect for various radial angles on the Imax at these heights are not linear.

 

For example: I post a similar model to the one above, except it has radials 109" instead of 72". Look what happens here.

 

I also post my notes for this 70' foot high test at different angles, and at 40' feet I did earlier.
