Motorised dish

    Just about to get into the motorised dish end of things and was wondering if any body knew from how far east/west (in degrees)can a sat be recieved. The dish I picked up is a 1meter dish.
    Just trying to figure out the best place for the mount.
    I was also about to buy a Powertech DG380 motor any good?
    If not any sugestions?;)

    Moteck SG2100 is reliable for me.

    It depends on the satellite (some don't have suitable footprints) and if you are rural and on a rise (lower noise), how far north you are and also to some extent on dish size. You should get about 20 satellites.

    58W is all Americas
    50W is all Americas
    Spot1 on 53W is feeds and weak here. Unlikely


    With everything good and very big dish you can go about 8 or 9 degrees above horizon.
    Realistically usually about +14 degree elevation with a 1m dish

    At 53N , -8W (midwest approx) minimum 14 degrees gives
    42E to 58W

    10 degrees gives
    50E to 66W

    In practice so, in Midwest there is nothing more east than 42E likely and further west than about 50W I think the satellite are all American beams.

    In South East 10 degrees
    55E to 64W. So you might think to pickup 56E, but you can't

    Points at Russia

    In South East 14 degrees
    47E to 57W approx

    see http://www.lyngsat.com/europe.html
    and http://www.lyngsat.com/atlantic.html

    Ignore beams/channels below 10.7GHz and above 12.6GHz as your LNBF can't receive them.

    Thanks for the fast reply Watty.
    So just to clarify not likley to get any thing beyond 50 degrees east of south and 66 degrees west of south(Roughley).
    That being the case would a southerly aspect for the mount would be best?

    One more thing 1 meter dish is pretty big anybody in a very windy area using one of these(Its solid)with a motor? We get battered down here during the winter southwesterlys straight in of the sea.

    The satellite Orbit positions are NOT the dish angles!

    Solid is best. The mesh rust and have no less of a wind load, sometimes more.

    you want maybe a 3" diameter pole and motor only just above bracket if on a wall. If free standing you need close to ground and a LOT of concrete.

    heavy duty masonry bolts, not screws.

    Assuming 52N and 5W

    42E is azimuth approximately 125 degrees (180 -125 = 55 east of South)
    5W is 180 degrees = due south
    45W is aproximately 227 degrees (227 - 180 = 47 east of South)

    Some cheap motors only do + & - 45 degrees of South.

    and Dishpointer http://www.dishpointer.com/

    The Swedish Microwave PC app is the best once you figure it.

    You need to use your own position (find it on Google Earth / maps ) for the receiver GoToX / Usals feature
