In the Twin Cities. I am a big Wpg Jets fan and was looking forward to the TSN broadcast of Jet games on TSN3. I can get 50-55% signal for TSN1 HD and TSN2 HD but only about 45% on TSN3 HD. I lose the TSN 3 HD signal with any cloud cover. I am using a Dish Network 500 plus dish mounted on the roof. I think I need to get a bigger dish to improve my signal. I would like a single dish solution. Any suggestions?
