Yes, but that's a VERY oversimplistic description. Study N0AX's ARRL 
book on the topic, to which I contributed, and/or this pdf of slides for 
a talk I've done at Visalia, Pacificon, and to various large clubs.

The VERY short answer is that everything that's connected to the rig 
must be bonded together by short fat copper AT the operating desk. That 
common point must be bonded to every other ground in our home, also by 
the shortest practical fat copper. In the shack, I mostly use #10 
stranded; outside, I use #6 stranded.
