360 degree turning circle

[johnc86]

this is my second post on the subject of setting up my new dish with disecq motor.

i am installing my dish on a t and k bracket with a long pole (to see over the building opposite).

i have a question though. most satellites you see on domestic premises are bskyb intalls with a fixed dish attached to a wall. even people who have larger dishes have them fixed to the wall. what i want to know is this; do people who have motorized dish's need the dish to be able to rotate 360 degrees, i.e. without turning and smacking into the wall??

even if there isnt anythng that can be picked up in these positions (i dont have a clue, im a newbi), you could surely, quite easily select a satellite in a position where the dish cannot turn to.

The broadcast satellites lie on an inverted arc with its apex at due south and curving down towards south east & south west. There is nothing located out to the north

The arc is only visable over a 120 degree section from approx 60 East to 60 West in the UK therefore more than that is pointless. Polar mounts restrict mechanically the movement to specific limits usually less than 120Deg. H-H mounts do this with either electrical reed switch stops or software stops

If your system was set up correctly this should not happen

No.. the absolute max is about 75e to 75w and that's not really possible in almost 99.9% of installs. Most try for 45e to 45w (90%) and some get a bit further... Sky is at 28e so you want to look 28 degrees to the west (right) to your middle (south) then it's 45 degrees either way..

Just to add, DiSEqC motors are H-H, i.e Horizon to Horizon. Which means that at the end stops the dish will be pointing at or very nearly to the ground.
