I just bought an oval dish. RCA DSA8900H, 18"x20", triple LNB. Trying to install it but can't seem to get a signal. I'm hoping that it isnt a condo complex that is 1/4 mile away blocking me. Can someone confirm Elevation and Azimuth and Tilt for this type of dish at zip code 06854? My receiver is telling me 250 Azimuth, 29 Elevation, 55Tilt. Thanks.
