last week i was puuting the dish up and it fell, i just found out that the pro who put it up can only install sly and freesat so i think he got the easy way out by saying the dish was warped i had the fortec star motorised dish up on a fta reciever and i was getiing 40 to 50 on the signal meter. there is a slight dent in the dish but i realised it was on the stupid FKU lnb anywany, so i connected the blade media up on my sly dish and i was getting 98 on the signal meter. so hi do i know if the dish is warped
