    Dish low to the ground and tent pegs. I have had mine set up in extremely high winds with no troubles. For travellers versatility and low cost is the go, KISS. I can't justify the several thousand dollars for fancy auto ones that may not work because they can't see the sky.
    As for other close rigs, it is amazing how close they can be and the dish can 'see' over the rig or even buildings.

    I think we forget at times that the dish isn't quite facing the Satellite like a spotlight but the signal is coming down at an angle opposite the offset LNB arm.
    This feature does allow you a bit of leeway regarding possible signal blocking objects unlike centre feed dish's.
    Anyone who leaves anything out at night not nailed down can guarantee a full scale Force 10 Land Gale will come up and blow it down, irrespective of what the weather forecast says.
    I stand unequivicably behind everything I say , I just dont ever remember saying it !!

    yes, tent pegs are the business. I have my dish ground mounted on a few railway sleepers. It blew over a few years back, so I screwed some eyelets in to the side and put four 8" tent pegs in to hold it down. Hasn't blown over since!!

    A few tent pegs fixes that problem. Have not lost an LNB in 6 years with a traveling Aurora set up

    While correct this is a little bit misleading, mounted in the same location the centre-feed dish would still receive the same signal (all else being equal).

    The only difference is the apparent direction the dishes a pointed. The offset dish will always appear to be pointed much lower than the satellite location (to the untrained observer)



    EDIT: Ive seen a few travellers setups, and also recommend tent pegs.

    Correct.... the signal path is identical for a prime focus or an offset dish, so there is no leeway for any objects in the signal path of an offset dish compared to a prome-focus dish.

    The only difference is the physical elevation of the dish... (lower with an offset). The signal path is identical.

    Tent pegs should always be used on tripods.

    Never mind possible damage to your own dish or LNB if it takes off in the wind.... the damage it could cause to vehicles, other property and worse... injuries to people are of far greater concern.

    I use 30cm lengths of hot-dipped galvanised reo bar formed into pegs to secure my 85cm dish and if in doubt, I add shot bags.

    Never had one even move out of alignment.
