I install in the souther eastern to near sout central region of michigan and sometimes north western ohio. For the 121 superdish that gets 121, 119, and 110 I set the elevation to 30, skew is 123, signal strengths for the 121 average around %80 but Ive had it just above %100 once and can get it into the %90 range more often.
Even though dbs dish's can be out of alignment and still get signal to a degrea the settings for each are specific so you cant set a dish to specs for 119 and get a 110 signal unless your mast is out of wack, same goes for trying to get the 121 with a dish set to 119 specs.
