the "standard installation" for dish has always been 1 dish, maximum of 100 feet of rg6 coax, and all exterior wall punches per receiver, all wall fishes, attic crawls, extra dishes, backfeeds, antennae tie ins (or cable tv) pole mounts or any thing custom such as tri-pod or bucket mounts are all extra charge charged directly to customer, prices tend to change from 1 installer to the next and it also depends on how busy the installer is and how many extras are involved on the job, most installers will work with the customer if possible but there are limitations per price of additional equipment and parts and of course time.
