Maximum length for RCA cable
Tom Franklin
like to run L & R Audio and Video from a VCR to a TV that is approx. 50
ft.away. The longest pre-made I've seen advertised is 50 ft.
Thanks in advance.

I'm not an expert on this, but for a run as long as that I would expect the
signal quality to be noticeably degraded, particularly for the video, or at
least that's what I've noticed when I've patched together long RCA cables.
One problem seems to be that the connection for the outer conductor doesn't
always seem to be very good, particularly the silverish ones which tend to
oxidize. Anyone with more technical savvy care to bolster or shoot down my
opinion?
The 6' cord I've got between my TV and VCR has 3 RCA cords sort of fused
together with a fatter cable for the video, and gold plated contacts. The
outer connectors have a sort of "spring" mechanism due to a C-shaped ring
that fits into a groove on the outside which helps to make the connection
more snug.
You can get F/F connectors to connect 2 25' cables together, or get a spool
of that fine coax that's used for RCA (sorry, don't know the guage, impedence
etc.) and solder the ends on yourself--all are available at Radio Shack, and
the F/F connectors should be available just about anywhere that sells stereo
equipment. I'd probably go for gold plated contacts, and try to find some
with the "spring" that I described.
Alternatively, I would send the video via standard 75 ohm coax and use RCA
connections to get HiFi stereo from the VCR.
