How poorly would an attic mounted antenna perform? Obviously worse than something outside, I’m guessing, but how much worse?
My office has one of those “side attics.” It has a half sized door. Mounting a long antenna in there is very tempting because of how much easier it would be than doing anything outside. It’s on the second floor as well.
I was thinking about putting my 2m antenna in the attic, I didn’t think about metal though. I have asphalt shingles but I have solar panels basically covering the south face. I’m guessing the brackets, panels, and wiring will all add up to my plan not panning out well.
