It is quite common for the Community association to disallow large dishes, but that can be changed by attending the meeting and lobbying for a large dish to be fitted serving the community,, On Urbanisation and blocks of apartments, unfortunately the builders build them to a spanish specification which provides for the reception of both Spanish terrestrial and Spanish Sat TV, usually of Hispat at 30W, (No Good for UK TV Im afraid).
The fitting of a small dish would probably not be a problem, and with a dish as small as say 90CM u should get programmes of 28.2E (The sky platform) such as True movies and a few other movie channels, Men and Motors,, loads of the free channels mostly shopping derived, (BBC radio would be available as would a host of other UK based radio channels)and then others such as Sky News , etc etc, further if you subscribe to a SKY contract package you will get a fair proportion of the Sky entertainment channels, BBC1/ITV is usually only available with a dish of 1,5M or larger depending on area.
There are quite a lot of rebroadcasters and they may be available in your area, these basically received SKY , BBC ITV etc, and then rebroadcast via a small dish or mesh system, best place is to look in the local mags etc,
There are other satellites available , which have a good selectin of programmes a lot of which are broadcast in English, ( YOu would need to sift thru all the channels and Satellites listed here to decide if it is of value to your (www.kingofsat.net )
Finally , if you have a good access to a broadband internet link (With a fairly high speed and bandwith) there are a couple of TV streaming sites that you can access and watch directly off then connected thru to your TV (see
https://www.liveuktv.com/index.asp ),, U can have free trial for about 7 days to see if the system is gonna work for you. or another option is that BBC and ITV CH4 are now streaming the channels via their websites, unfortunately they have got some form of restriction on that means you will have to pay and download a proxy switcher ( See here
http://www.shareup.com/Proxy_Switcher-download-27045.html ), which stops the distant site from locating you and therefore if you can find a proxy in the UK you should be able to stream direct!!
On the question of your TV, for about the last 4/5 years most TV's have autoswtiching to choose the RF receiving system IE Pal G, or PAL I or Secam, and even the america NTSC standard, so you shouldnt have any trouble receiving channels, in any event any form of digital receiver using a scart lead to your TV will get around that problem.
Thats about the limit of my current knowledge on this subject,
