Buy an outdoor antenna and stick it in your attic. If you can fit it there it

will work just as well.

It MIGHT work, but if the attic is trusses just forget it, while you might squeeze it in it will be impossible to rotate.

plus rain or snow may drop signal strength. and during weather emergencies is one time you really need tv.

antennas are far better outdoors........

a roof covered with snow or rain acts as a blanket that can kill signals
