First minor point: coax may or may not be viewed as a "Faraday cage", depending
on whether or not a balanced drive scheme is used (i.e., if the signal return
current is carried over the "shield", than it's not stricly a "Faraday cage.")
Now, major point: regardless of how well the cable company keeps undesired
signals off their cable, they *can* and likely *will* enter either at
the converter box or in your tuner (you don't mention whether you
use an external converter or use a "cable ready" TV). Consumer electronics
are notorious for poor shielding.

If the local channels are on their proper frequency on the cable, then I'm
assuming that your set's tuner is doing all the work - the above comments
apply. Connecting the external antenna for the local channels may in fact be
the only solution. Is this really a problem for taping? How often do you
tape shows from both local stations (which are not available from other
stations on the cable) and cable-only stations, in the same "unattended"
period?

Unfortunately, some type of shielding may be the only answer outside of
pulling the antenna swap - wrapping your house in tin foil is, I presume,
unacceptable. :-)
