Well as mentioned here, in Socal you can get it with no problem. But just to let ya know in case you were wondering, this Televisa Tijuana is not like the one from Mexico City (Canal 2 de las Estrellas). In fact, they show diffrent programming most of the time and it has nothing to do with the different time zones either.
So when you find it yourself, you wont be surprised in case you thought it was just like
Canal 2.
BTW: If you are still having an issue getting this channel, try it with a much larger dish like 100cm or even the 1.2m.
Here is the link from their programming schedule so you can see the difference in
Tijuana canal 12 and
Canal 2 Mexico City. Even their famous
NOVELAS are completely different from both channels.
