The antenna is delivered with a complete package (fixing, etc ...) and even a compass, even if it allows ps fine tune the orientation. Two small caveats: if need strong lateral offset, fixing delivered is a bit limited, I had to "tinker" a bit to be able to fix it properly. On the other hand, the score should be VERY accurate approximation and allows less a parable "classic" intelligence but took it turns out that it is common to all the antennas of this type. Otherwise, once installed correctly, the result is very good and the reception quality is perfect.
