I was at an install today that did not go so well... I'm fairly new to satellite installation. The company I work for recently-ish became DirecTV dealers. I've had next to no actual training... I've pretty much figured it all out on my own by much trial and error. Here's the skinny. I have a brand new dish setup that I have a slimline 3s LNB. The dish is located on a big pole shed. I have clear line of site, all the adjustments are set for my area, (tilt, elevation, azimuth). I'm using the DirecTV AIM meter. I've never had any problems with it until today. I connected the LNB to the meter, did a coarse adjustment of the azimuth until I got a locked signal. I then performed the dithering process successfully. When I went to perform the EIV. That failed. "X" across the board. At first I thought it might have been a bad LNB. Swapped it out with a new one... same thing. Failed EIV. I'm kinda at a loss... Is it possible that I am getting interference from all the metal in the building and the meter is locking onto a different satellite (i.e. the 110 or the 119) and it can't tell the difference? Any help is greatly appreciated.
