The directions on this page are very good except they do not mention a fork in the road between the gate pictured and the antenna towers. You come to this fork after hiking for about 20 minutes past the closed gate. You will also know the fork because there is a cattle grate just before it. If you go straight, you come to an older antenna station. You know it isn't the correct antenna station because you have a good view of "la tetilla" some distance away. But, if you take the hard right at the fork, you will come to the antenna base they mention in the post and the way up to "la tetilla."
