TV Reception

Just been on a  CL site near Chirk and we were having problems getting any TV reception. WE asked and was told that the caravaners sorted it out themselves. WE never got a TV reception there all week. In fact another member arrived and he asked us the same question NO TV reception. The father of the owner later told us that there was no TV reception on site - this must have been known ! BUT it is not made known in the site directory. Are there many sites like this One ?
