At a later date I am going to call in someone else to sort this. There are things here that I am not truly happy with. Some courses of brick are hidden behind facia. Not a bum deal - but could have had a better one. Your opinions are welcome!!
The install doesn't look too bad, the height of metal above the brackets means that the dish could be raised a tad just in case there is another satellite at the end of the arc to view.
The T and K brackets used are the shortest I've seen and these should cope with the pole used, and it looks like the proper scaffold stuff, which is about the best for this system.
The cable can be pulled back slightly from the LNB clamp end as there appears to be enough in the drip loop.
Post a couple of images of the dish side on, it may be possible to determine if there is a small warp in the reflector surface that is draining the overall signal. The LNB is also at the extreme of the clamp, fine if the dish was peaked before locking up, but I would have expected optimum signal with it about 25-75% of the way.
What else are you not happy with, apart from the lack of 7W ?
