    Here in the L.A. area, Comcast (previously
MediaOne, then AAT) uses quadshield to comply
with FCC regulations regarding signal egress and
to protect their own cable infrastructure from through-
the-air signal ingress.  These environments do vary
geographically, and in rural areas, non-quadshield
RG6 might be in use.  But in dense metropolitan
areas, quadshield is specified.

     Quadshield is not as important for satellite
installations, and it isn't used here for satellite
intermediate frequency cabling (i.e. the cabling
between the LNBs and the receiver) because at
those frequencies (roughly 1-2GHZ), signal egress
and ingress are not much of a problem.

     Quadshield RG6 is a little wider, though, than
regular RG6 cable, and it does present a minor
problem when following manufacturer's recommended
minimum bending radii.  But if you want a good clean
signal, it's the way to go for CATV, and it can't hurt
for satellite.  BTW, a good template for minimum
bend radius is an old CD.  A CD has a radius of
about 2.5" - which is about 8-10 times the outside
diameter of RG6 QS cable.  If you place the CD inside
the bend of the cable and the cable and the CD only
touch at one point, the cable's bend radius is OK.
If they touch at two points, the bend is too sharp.
If they touch all along the edge of the CD, it's marginal.
