After so many ionizations the gas tube will fail and won't clamp on the next strike.  For a time Polyphaser made a test set to verify the function of the gas tube.  We use those at work to test those in use once a year and every year we find a few that have failed.  Polyphaser quit selling the test set (FIST4) several years back so one will need to find another way to test them....maybe a meggar.

Cecil,

That's a good point. About a year ago I was having problems with my 
Steppir..after replacing coax, doing lot's of testing on the Steppir 
control box I started replacing all items along the path and discovered 
the PP on the grounded copper board at the base of the tower had gone 
'south'...
