depending on your dish .74 (oval) or .98 (round)
here in michigan you should hopefully see around a
(.74) 80 recieve and 75 crosspol
(.98) 90 rec and 80 cp.
this would be optimal and is sometimes not reachable.
Let me leave you with this ....
I live 45 minutes from byron center, and may be able to help you out. nothing is guarnteed other than it will cost you some cash to get me there.
another thing that can be a factor occasionally is the type of cable used. some techs use the cheaper 2.2ghz or forbidden 900 mhz cable. direcway standard is 3.0ghz or better swept. depending on the lenght of your cable run you could see some performance increase there.
