|I too have a 2nd floor "shack" grounding issue, with a length-to-ground rod distance of about 17-18- feet. I have heard about a system published in 2003, that addresses electrical & RF grounding by using RG-8 coax with a capacitor at one or both ends of the coax. The length of the coax between the ground rod and ground bus at the equipment is then, not an issue. Does any of this make any sense. I know at least one retailer who sells capacitors for this "system" and have also had another ham retailer recommend it.
