The Skylink package that my wife will use is on Astra 3a.
The chimney would be good because it would be much more discreet but I guess we'll have to go for the front of the house

I don't mind it but I hope the neighbors don't complain.
To make matters even worse the place where I'm getting it from only has 110mm Triax dishes in stock. They can get 100mm but I want it installed on Sunday and I'm too impatient to wait. I guess 110mm equals better reception from satellites but not so good reception from neighbors.
Is the t&k bracket with pole a better/stronger route than the mount which I think is called an arm mount?
I think this motor says that it's suitable for up to 1m dishes – is the 1.1m pushing it too much?
And I'm going to go for a STAB Motor – I think it's the HH100. It's £70 and i know it's supposed to be slower than the others but apparently they're quite sturdy and reliable.
