Ive read all the post here about this amp and have seen all the diagrams that sonora has. What it doesnt show is a best location for this amp. The diagram shows 100' from dish to amp, then out of a 8 way you can go 250' At a show room we have a dish about 400' from the booth. Right now they have dish >> 400' rg6 >> PI >> LA141R with 24v >> 4 way Its working most of the time, then starts searching. Would it be better to have the amp closer to the dish and be power by the PI? There is no power source by the dish. Right now its a 21V PI, and they are bringing out a 29V tomorrow. Not sure if moving the amp would improve anything.
