Richard has debunked much of the FUD about the foil/braid outer conductor.

Not wanting to hijack the thread, but for all the paranoia about whether
the outer conductor works properly and at what freqeuncies, the discussion
has ignored the risk of poorer performance at low HF for such cables with
CCS inner conductors if the cladding is inadequate.

This effect does not seem to worry most ham users of CCS ladder line, so
perhaps ignoring it for RG6 or RG59 is in keeping with that.

I use RG6 selectively, selected cable and selected connectors on selected
applications. There is potentially a good match, prospect of low cost and
good performance.

Inspect a sample of the cable you are considering, whether it is RG59 or
RG6, or any no-name cable for that matter. If through braid leakage is
critical to your application, you are more likely to find no-name RG59 with
higher through braid leakage than RG6.
