There is something that does not make sense about this. The thermal
expansion of the plastic insulation in coax is about 10 times that of the
center copper wire. The plastic basically determines the length of the cable
between the connector bodies, so I would think the wire would actually
protrude more as the temperature drops. This still could be a problem since
that might make cause the center connector to make contact with a grounded
shield in the splitter.


I saw a lot of damaged splitters where people left the center
conductor too long. It would distort the spring in the 'F' connector
and make it unreliable. Small TV coax has a copper plated steel center
conductor & a steel braid over the foil shield. The foam insulation is
too thin to provide much insulation, so the expansion factor is very
small.

Ohio back in the '80s.
