In regards to the above posts; I considered the possibility of the roofer bending the arm so I studied the arm closely and see a distinctive die mark, a machine stamping so to speak as if the arm was placed in a die and pressed to form the bend, the paint is not scratched or shows any signs of tampering, besides this, if the roofer had dropped it, it would have bent the side supports instead because the feed arm is lower and if it had been accidently bent, the impact would've likely been from the bottom and not from the top. There's no doubt that the bend was made at the factory in a die press, no doubt whatsoever.
As I mentioned, the panel nut is only on one side of the rectangular tube, it only permits the arm to be installed in one direction so that the end user could not possibly mistakenly install it upside down, I had to drill a hole in order to do so. I used to work for a manufacturing company where they made similar bends in tubular material in the same fashion and it would be easy for a worker to accidentally insert the item upside down in the press as there is no keyed device to prevent such an event. This is just a simple piece of rectangular tubing with a panel nut on one end which is typically installed before making bends in the tubing. A mistake of bending it in the wrong direction is very common if the worker isn't paying attention, maybe it was Monday morning, EEEK!
With the tube inverted, the LNB alignment points directly to the center of the reflector as before it was pointing below the center. The end results after the modification produced signals from a low of 58% to 81% QS vs the 0% to 32% QS on the same TP's.
As to the roofer, the coax wasn't cut but yes it was disconnected. I concluded that the roofer likely smoked both the receiver and the LNB when he disconnected it. My friend said that everything was working before he removed the dish, she didn't usually power off the stb or did she know of the danger of breaking connections with it powered on. I first discovered the dead stb when I went to her house to reinstall the dish, I didn't have any field equipment with me for testing, I assumed I could use her stb for reaiming but I found that it was dead. The roofer was not the only one who tampered with the cables either. It's a very long story but I will say that when she had DirecTV installed, they too tampered with the cables in the attic and I discovered that they used part of my FTA cabling that went down through the walls. And to top it off, my lady friend is totally clueless about anything technical, she's either the master of confusion or the end product thereof. I have to be very specific when I ask her questions, I have to first explain any details before extracting any sensible information from her so I can understand what she's saying, it's like talking to a 5 year old child, maybe worse.
So somehwere along the line, somebody or somehow the stb's power supply and the LNB were toasted at the same time. She lives 100 miles away so it's not so easy for me to drop by to check in, lots of things could happen between visits.
