The cabling looks a little sloppy (sorry scooterz), the ground wire should not have that fork or ring connector attachment, and I am curious as to where the ground wire actually goes. The first picture just shows the ground wire going directly to the non-penetrating roof mount but then disappears. Probably just the way the picture was taken but it looks odd. Personally, I would have grounded to the base of the mast, not to the U-bolt holding the pre-amp to the mast via that fork or ring connector. The circle loops are not necessary when a longer drip loop could have been used and the cables attached to the mast to give a cleaner look and have less chance of damage occuring to the cable, since they wouldn't be so exposed. Finally, the cable from the antenna ahould have been attached to the top of the mast to keep from moving due to the weather. Well, at least that is how I would have installed it anyway.
