[mythtv-users] Off topic - can someone identify this connector please, I think it's US standard.

[Another Sillyname]

On the back of a HTPC I have an antenna input connector, in the image
below it's circled in red.

The connector is about F-Connector sized (perhaps slightly smaller)
but has no thread so instead is a push-on.

I've googled around but it's one of those stupid situations where if
you don't know exactly what it's called you can't find one.......

I'm looking to source a connector that will allow me to feed in a
standard UK aerial feed (I'm happy to use an F-Connector adapter if
needs be though).

If someone could tell me exactly what the connector is called (i.e.
SMA, Push On F-Connector, whatever.....rather then generic terms like
mini co-axial which means different things to different people I'd be
very grateful).

Thanks in advance
