The concrete base is not a good insulator.  You could drain any static 
charges by using a hairpin coil match or a large inductor.

I'm considering replacing my 1/2 square with a 1/4 wave vertical. The wires
keeping breaking in the storms. What I would like to know is if anyone is
using  Rohn 20/25 as an 80m vertical. I'm sure the physical size is shorter
because of  the large diameter. If you use a concrete base, that should make
virtually  insulated from ground. Another consideration is  lightning
You can disconnect the feed when not in use but would a  gap type arrestor 
sufficient to drain static charges?say a 1/4'' one. Anyone  out there using
something similar?
