Spanish Terrstrial television has to be available to eveyone either by aerial or cable - this is Spanish law. Unfortunately there is no such provision for English language TV. On some resorts TV and internet are part of the Community fee package, this is not the case for Terrazas, a vote taken in 2012 meant that no communal contract was madewith a2z - who own the infrastructure wiring.
Some blocks have installed communal dish in the roof space, but this only gives free sat TV. - (permission is required from Resortalia.)
An alternative is to have a communal internet aerial installed (permission required) by a company such as TV Horadada. Their costs are similar to a2z but they do offer a faster rate and the ability to take out short term contracts.
Hope this helps, if you need more information please contact me.
