We have one tower, that as a test, we did not do any grounds other than the power ground. Everything else is grounded by "default". What I mean is the mast attached to the tower is grounded simply because it is attached to the tower, etc. This site has been up for 2 years with no issues. The luck factor has a lot to do with lightning. This is not the norm, was done as a test.
