When the centeralized dispatch for the Police Department I worked for the LAN in the office was what is sometimes called a cheap-net, all Coax cable with BNC connectors.. We had several crip-on Connectors simply fall off the cable.
F-Connectors do that too.
But thanks to this thread I am seriously considering switching the connectors (Currently F) on ONE of my cables to BNC, I have 3 TV's in this coach, one is more or less portable (The others are bolted to something, this one is not) and the connection to it is flakey,, not sure which of 3 connections is the problem child but I can fix that easily enough when I upgrade the cable ends.
(In the bedroom I have a computer.. If I want to watch TV and Compute in the old days I had a single TV/Monitor with Pic in Pic, but when it died the new one can be a monitor or a tv but never both at once, so I put in a 2nd TV, when traveling this 2nd one goes in the laundry basket with the dirty cloths (A nice soft cushion) and I can also take it outside to use there, or put it in other palces as needed. But the connecitons are flakey I keep having to "Bump" the coax, Fairly sure it is a bad crimp on but have yet to get a round tuit needed to fix it.
