If there were a high-current fault near the chamber, there might be a hazardous voltage developed between the shield of the antenna cable and the items grounded to the chamber. In USA, the voltage might be more hazardous to the equipment than to any humans in the area. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better.
