SKsatellite is right, he is a great installer! The paint is not a problem, the RG59 should be replaced as soon as possible, but thats not the problem, and grounding is not the problem but HAS to be done. Make sure the mast is PLUMB near is no good, leave the bubble level in place when you put the dish on as the weight pulls it off plum, so you will have to recentre the bubble when you get the dish on, then set skew and elevation for your zip code, and if that dont work its a bad switch, or trees, good luck!
