Most of the things I read suggest that the extra sheilding is only really
useful if you have a strong local signal you want to exclude. More problems
result from poor connections, according to posts by satellite installers,
than from using a cheap foil/braid shield.

That tells you a lot about the people posting. The quad shield is not
to prevent other signals getting in, it's to prevent the ones inside from
getting out.

I'm not in the US, so I don't know if the VHF/UHF TV channels were abandonded
by cable companies in the switch to digital, but you can be sure that any
now unused bandwidth won't stay unused long.
