My Charter contract will be up in a few months. I will be switching to Dish Network. I"m looking at a 500 with dp twin LNBF for 119 and 110 and a separate 500 with dual LNBF plus I bracket for 129 or 61.5 but may not be able to see 61.5. Is there a Larger Dish Pro compatable 24" or 30" dish I could use for the HD sats? I live in WallaWalla WA. 99362 the 61.5 sat is at 13.3 elevation here, so may have to use 129. Any recommendations are welcome and thanks for the help.
