I received a new tower base from Hy-Gain and the rebar is somewhat rusted. Is this a problem? How will affect Ufer grounding? I have not installed it yet (mainly because it came in bent and I insisted on a new one). Thanks, Allen Ross Brier, N5XZ Richmond, Texas (281) 342-1590 (281) 342-0940 (FAX) (713) 705-4801 (Cell)
