This is BITOG where many of the members are OCD (maybe even most!) and half-assing stuff generally isn't well received. Ergo, you should in no way be surprised by the responses given.Wow everybody is making this harder than it seems. Not everybody cares about RF interference or the perfect setup, he's not using it for a data center. I googled up Cat5e male to female extensions and got virtually unlimited results. Here's the google results for you.
I'm in the middle of having a medical building re-wired with CAT6A because the existing is a mix of CAT3, CAT5 and CAT5e in varying qualities and there are all sorts of weird and wild performance and connectivity issues as a result. Couplings in the ceiling? Check. CAT3 cable and wall jacks trying to push Gig-E? Check, CAT5 cable and wall jacks trying to push Gig-E? Check. $20 d-link unmanaged switches also in the ceiling? Check. Departments daisy-chained instead of home runs? Also Check! A complete ****-show because somebody was fine with it being done in that manner or totally oblivious to the potential issues allowing it to be half-assed introduces.
A coupling introduces a point of failure in what should be a home run. Cars and trucks are exposed to a myriad of temperatures and levels of humidity that can cause corrosion in these sorts of connectors, which is why couplings on surveillance cameras have weatherproofing and seals to prevent moisture ingress and, if one was forced to use a coupling, should be the minimum standard (using a weatherproof junction).
This thread went the expected direction.
