I thought AM was a time of day.
I used to wire the "antenna" to a screen on the window, I could pickup stations a state away... some window screens are now fiber instead of metal, but some still work.
...an overhead hoist setup that is removeable?
I RENT my house & 2 car garage, so I don't want to (can't) attach the 2 ton chain hoist to the trusses like a normal builder would. I had the idea of making a "bolt-together" A-frame setup inside the garage that I could un-bolt and take with me...
