Hi, ive been looking at the snipe satellite system as im fed up of faffing around with my portable carry case system ive used various signal boxes to tell you where to point dish but all are pretty useles especially as they have now changed position of some satellites, my question is can I just place a snipe or similar system on my roof on arriving on site and be able to take off when leaving as if I were to change my van it would be expensive to swop over
