This is a very cheaply made antenna. I certainly would not trust it outside, especially with our Canadian winters. The instructions are not very useful either. The pre-amp has a coax input marked "ANTENNA" which you attach to the single input on the antenna. This does turn the rotor when you press the button. There is then a coax coming out of the pre-amp unit that is marked "TV" which I attached to my television and could not get even a ghost of analog, let alone HD for that matter. There is also curiously another coax output on the pre-amp unit that is blank...my thinking is that this should be attached to the exterior of the antenna somewhere but there are no real leads found nor is it mentioned in the instructions. Very disappointing but understandable considering the price.
