Hi Alyson & John,
Big welcome to the Los Olivos forum - regarding satellite tv and sharing a dish, then it depends on whether any of the four in a block want Skyplus - basically you can have upto 4 feeds from one dish, but Skyplus requires 2 feeds.
I have seen a number of people have already bought the huge grey 1 meter across dishes, which don't exactly blend in with the scenery - if every apartment bought their own, the place would look like Jodrell Bank ! I would encourage people to share and minimise both the cost and the effect on the attractiveness of the development (and I have to say it is looking pretty good at the moment).
Quite a few people have bought sat tv dishes and/or air-con units through D-Match - they install LG a/c units which have a 7-year guarantee and whose maintenance guys are based just down the road in Garrucha.
So I would get in touch with Drew & Karen (10a) and Linda & Steve (9b) and leave a note under the door of 10b to see if they want to club together and save costs (I think the dishes are around 500 euros installed).
All the best
Dave & Ailsa, 2A
