Directv has sent out 3 installers to try and get this dish aligned properly and they can't get it right..... the dish is on a non-penetrating mount on the rooftop of my apt. i don't have the equipment (signal meter) to do the alignment myself, so if anyone knows a good tech that i can contact directly i would appreciate it very much. alternatively if anyone has the equipment and would be willing to give me a hand that would be very very much appreciated. the problem is that the signal on the 110 sat 12 transponder is flaky and all over the board. right now its showing a 45 on the HR20 signal meter (transponders 8 & 10 are 80+). i've had the LNB replaced, checked all the cables and took the multiswitch out of the equation (plugged IRD directly into the sat line to the LNB). the problem comes and goes to say the least. it might be ok for 24 hours and then drop for a couple days and then back to normal.
