Hi Thinted,
I own in La Mirada, close by you.
I have seen mesh ariels on El Rincon's rooftop, you can pay monthly, plus an installation cost, to have digital signal from a company called Cina.
We currently pay 19€ a month, that gives all UK channels, plus Sky Movies, Sports etc.,!
So much cheaper than the average package of about £35 per month in the UK!!
