Not necessarily true. If, for example, equipment in the shack is not
properly bonded together, an antenna close to the shack will put a lot
of RF in the shack, which will induce RF onto cables connected to
equipment, and is likely to couple into equipment. If an antenna is
working as an antenna and it's close to the shack, it WILL put RF in the
shack -- that's what it is intended to do!
Proper bonding is described in this set of slides

and in N0AX's new ARRL book on Power, Grounding, and Bonding

With effective common mode chokes on the antenna and feedline, you
should not have to use ferrites on every cable in the shack - a much
more sane answer IMHO.
