Anritsu FAQs
When testing sites on power transmission towers do I need to worry about ESD damaging the Site Master?
Yes. If you are testing the line with the antenna attached, there is a good chance that the Site Master could be damaged by ESD. This happens because ESD gets onto the center conductor through the antenna's elements. It is safe to test with a load or short because there is no path for the ESD to get onto the center conductor.
