Pretty sure I have the evil of all rf in my station. A ground loop. Do line isolators in front of a antenna switch work? I've done some research but I see long drawn out solutions with capacitance, reactance and 1/4 wavelengths of bad ground ju ju.and I can't see how to ground each individual piece without the ground strap touching each other and making it worse .Im trying to understand this shock hazard. Anybody dealt with this in there setup?
