Don't forget that you live in Arizona now. Your attic will very quickly become unbearable.
Nice work, Rich. I was confident your new shack would be impressive.
Rich where would I locate racks like that? Do you make the cut-outs or are they commercially available ?
I really have no choice. The new house (as was my last home) is in an HOA that prohibits outside antennas. While I haven't lived in a home with outside antennas since I was in high school I don't have the reference point so much.
I can say that comparing the results with my attic antennas to friends with outside antennas, the outside ones are always going to be better, all else being equal. Add up the elevation and the lack of reflection from other metal items in the attic and you will always be better off with the antennas on the roof.
As Shreck once said: "Better out than in". While the context was different it still holds true.
