Being close to a rig does NOT make you close to RF. RF field strength
is generated by RF current flowing in an unshielded wire. It does not
leak out of a well shielded box (or at least very little). The RF is
out surrounding the antenna, not next to the rig.
A ham shack is hot with RF only when RF current is flowing through the
shack -- for example, when common mode current is flowing on the
transmission line. I had a lot of RF in my shack in Chicago when I
loaded a long wire (on 80 and 160) that ended at the antenna tuner in
my shack, or a 30M vertical that was 10 ft away out the window. The
shack was hot with RF because it was close to the antenna, not close to
