Super dish is DishPro technogology. Have not run into any bad DP 34s as of yet. Not saying it can't happen. You need to make sure you have dish aligned properly. Receivers will not detect the 105 or the 121 until you download if it is a new install. After download you have to do another switch check and check the superdish option. Make sure you are getting the 110 and 119 sats before checking for 105 or 121 sats.
