I'm sorry, I have to respectfully disagree.  If you have a balanced antenna 
system, or even an unbalanced system with RF properly choked off from the 
outside of your coax, there will be no RF on the chassis that 'as to go 
somewhere'.

In addition, it is very difficult to provide an RF ground at HF.  Even the 
8-foot wire you mention will have significant impedance.  And a ground rod is of 
absolutely NO use for RF grounding, although correctly applied ground rods may 
be useful for lightning protection.
