Even on the ground floor, before I put it in the attic, I'm getting much better signal strength than from a square panel antenna. Where I live, south of Austin, all of the major stations are in the 90-99 range. A few minor stations have broadcast antennae at other angles / directions. They're still coming in quite clearly, despite being 55-80 out of 100.
Once I get this installed in the attic, I expect even better performance from minor channels that I don't care too much about.
It comes in a long package, and assembly is going to take awhile. Maybe 30-45 minutes.
It's a mixture of plastic, aluminum and steel, but I expect it to last.
