Great antenna, but I recommend everyone before the exercise to allow the antenna on a table outdoors once the satellite search. If product is not visible in Satelitt outdoor access after several turns, the data must be aktuallisiert via an Internet connection (update) once. Download program (driver but could not be under Win 8, but under Win 7 install), download transferring data to the program and then send to the controller. Since the antenna is reliably with free "view" the Astra Satellite, Satellite others I have not tried. Fascinat how fast he ASTRA Satelitt place by GPS. The antenna is located by the GPS positioning appear automatically on the latitude / longitude, and aimed the antenna from direct accordingly, ie any misalignment (also in our latitudes) is normal. The manual pdf I had in German and it is understandable. Have requested driver for Win8 at Sathelden via email, this would let me know if drivers exist ... let's see if it works eventually.
