You can't use a fiberglass omni at the top of a tower and expect it to survive a strike unless it has a copper groundrod built inside of it protruding from the top in which it was designed to take a strike. Learned this from various HAM radio operators. Only 2.4ghz omni I know of that has a metal frame and can survive direct strikes are slotted waveguides such as the various H-POL omni's you see. If I'm going to use a VPOL omni I make sure I'm not the tallest guy on the tower.
