Yes, but it depends on how militant the residents are and if the management agent is proactive. Let's be honest, SKY is a hell of a lot better than NTL but satellite dishes are unsightly strewn across a complex. There is a balance to be struck. It's a pity developers don't explore the installation of a communal roof dish more often. I'm sure SKY would subsidise this in the same way cable and broadband companies do to get exclusivity.
I used to live in an apartment complex and did broach the subject of a communal dish with the management company. After assuring me that they would look into it nothing happened and I ended up NTL digital.
I know for a fact that in the estate I live in now the developer had a deal with a cable company and that is where the no satellite dishes for antennae for aesthetic reasons rule came about. Frankly I chose to ignore it and so did the vast majority of the other residents.
