Wow... That really is lucky. How did you go about running the power/antenna lines and the antenna as well?
It's not a bad scanner, my family accidentally bought one so we just leave it running in the garage. I only have our FD, the town next door's FD, and FRS channel 7 because we commonly use it. Works out well.
It's a nice scanner, just a bit hard to program in my opinion. The cops here all have one in the squad cars, I think.
