Thank you for your help so far. I've decided to do a gable install on my house, here's my updated report @ 35' (if it changes anything?)

Would anyone recommend installing a rotator just for fine tuning? I don't have a 30' ladder, so I would have to rent one every time I have to get up on the roof. I would keep it aimed at 154 degrees towards Chicago. What would be a good basic rotator? (don't need a fancy remote for it)
Also, I assume I need to install some kind of grounding wire to the gable mount? Can someone point me to a guide how to correctly install it? Thank you!
