Assuming you're asking about Claro TV, the Claro channels on 70W are on the South American and Brazilian beams. The South American beam of C4 doesn't quite reach Texas. I can see a hint of of these signals here, on a spectrum analyzer with a 1.2 meter dish, but they are a long way from receivable. They are probably a bit stronger in Texas, but I'd guess they still won't be receivable. I get the Claro channels from 50W OK.
C4 does have a North American beam that covers Texas well, but I have never seen any type of signal on it.
