Hello, I have a question about the two Dish Network Dishes I have. They are both the black "Dish HD" dishes. On is aprox. 20.5" x 25.75" and the other one is 23.5" x 30.75". They were originally installed on my house so I could receive all Dish network programming including satellite 118 for the filipino channels. I want to use one as a portable one while RVing so my wife can see her filipino channels and I can watch stuff I like. What dishes are they? Will the larger dish enable me to get the satellite signals I want?
