that's a correct/good idea, however, it's most likely redundant.
the cable is grounded via the receiver, which is grounded to the electrical service panel, which is grounded by the rod outside. the service panel ground rod and the mast are both grounded in the same soil. assuming the soils are similar(will be unless soils are significantly different), the potential difference between soils (dish and cable) is zero.
