We are using rg223 as fly leads and heliax up to the antennas .I feel it is a loose bolt in the tower and it moves when the tower twists .apart from checking each bolt .What I was wondering with earthing the coax at the top and bottom of the tower was if it tends to improve the shielding of the heliax so it ignores Any static on the way up the tower .One other thing I might be overlooking is one repeater on site had its ant damaged due to lightning and it could be the cause of the static but the users of that repeater don't find any problems with their reception at all .Its affecting everyone else though which is strange .

What you propose should be practice and not an experiment. It is just good practice to ground the antenna mast, coax and equipment to a common ground. Otherwise where I am located in West Florida the setup might last a month due to lightning. You should also use double shielded coax or hardline for your coax run and in your equipment.
