I am at 55.71 N lat and 121.63 W long.  I used GeoSatFinder at satellite AV to make a dish aiming coordinate table.  The satellite directly south of me is 121 W-Echostar 9-Galaxy23.   The elevation is listed at 26.5 degrees BUT I am wondering if these settings are for a 90 cm KU dish.  MY 10 footer does not adjust that low.  I run out of threads to hold the dish.  Is there a better calculator to use for a C Band Dish?
