F Connectors

[Dave Plowman (News)]

Came across a funny today - a DAB tuner with the input F socket 'square' at the end rather than tapered. Which means certain makes of plugs simply won't grip tightly - even with the nut tight the body still spins round. Can't do much for the signal.

Not sure I understand, I thought they were all square

being square, you can see a slight chamfer on the end of the ones in this photo.

shows the plug which screws onto the socket. And it is the socket that was unusual in that the end was near completely square - just like a thread cut through with a hacksaw. Most of the others I've seen have a small taper. And if you look at the design of the plug, the socket end needs to clamp on the plug body - with this arrangement the thread bottomed in the nut part before gripping the body.
