Having worked on broadcast sites for over 20 years, I'll suggest that it is 
possible, but that this application sounds suspect in unrelated other ways.  
I've seen a 4" copper ground strap cause an increase rather than decrease in 
RF pickup in some mixers.  In some circumstances several feet of 4" ground 
strap can have a differential from end to end of several hundred volts of RF. 
 Grounds of all kinds can under some circumstances act as antennae.
