I have a cutomer building a new house, which he will have a ham radio. something about interference all outlets(not lighting) need to be on same circuit. he said he brought a 30 amp into his existing set up(at old house/future old house)and tapped 120 volt outlets off that, and drove ground rod down. I suggested putting a sub-panel and feeding ham radio 30 amp/240 volt outlet and 120 volt outlets from here.
he wants to drive a ground rod for radio, but i think that would be a violation since it wouldn't be tied with service ground rods. wouldn't the ground be well established with the four wire i feed sub with? that it would mitagate need for additional ground? and if additional ground rod neccessary then it would have to tie with the two at service which really would be redundant...of course the other suggestion could be to run 4 wire and a single gounding from service rods to sub panel. dont know much about ham radios and this interference he's worried about.

any help, comments appreciated.
thanks,
