Hmm.  Does this engineer work for a company that sells connectors or "high end" cable?  Tightening an F connector will only affect
the ground (shield) connection.  It has no affect on the center conductor on which the signal rides.

I usually use gold plated connectors for audio gear though in all honesty none of the cheaper ones I used to use many years ago ever
gave me any trouble.  In fact, for A/V I defy anyone to tell the fdifference between gold-plated and cheap, push-on connectors.

That's strange.  It has never happened to me and I always use finger tight connections on A/V gear.  Perhaps the gentleman is
speaking of connections exposed to the elements.  In part of the snipped passage he mentions the effect of wind on the connectors.
