Once you get a good grade of RG-6 with the foil and braid, does the quad
shield cable really do anything for the home TV usage ? I think it is all
just some hype just as the Monster cable is for the audio people. Sort of
like the 120 volt line cord being special and costing $ 100 or more for a 6
foot cable. Even it it did something, there is 25 to100 feet of regular old
wire to the breaker box.

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.

i.e possessing less facts or information than can be found in the Wikipedia.

Worse..
Several cable channels overlap the aviation VHF band, and as one might
imagine, the FCC comes down on the cable operator pretty quick if their
physical plant is leaking any significant power at those frequencies.

As noted elsewhere, the last thing the cable operator wants is to
discover that some cable inside a customer's house is radiating. The
cable operator is responsible for signal leakage all the way to the
point of use (e.g. the RF input to the TV).

This is unlike the regulated telephone company, where there's a clear
"demarcation point" that separates the responsibility (it's even called
the "demarc" colloquially.. it's at the cable point of entry to the
house, and has a phone jack and plug installed). For phone stuff, if
there's a problem, and they come out, and unplug the demarc, and the
problem goes away, YOU get to fix it, because it's on YOUR side of the line.

It's a sort of trade.. the cable company is very lightly regulated, and
can offer services and such all the way into your house, but in
exchange, they're also responsible.
