I have a question about grounding a base antenna mast. The installer for my Dish TV, mounted on a 4 ft pole, grounded the double coax to the steel frame under my mobile home. The installer for my satellite dish, mounted on a 6 ft pole, did the same. I plan to put up a 12 ft pole for my base antenna. Can I ground this pole the same way to the steel frame. For so far I know this steel frame is grounded to the power line which comes in my mobile home. The power line is grounded to a 8 ft bar 20 ft away from my home where the power line comes in from the power company. Please advice.
