The MMCX connector

[subwoofer]

Dear All

I have just received an external antenna for my PiN 570 to use when I take it in a car with a coated front windscreen.

The MMCX plug clicks into the socket OK (and the antenna works well), but what concerns me is that it has quite a lot of play. You can easily wobble it from side to side.

I would expect the plug itself to not have any play, but have never used this type of connector before. The socket is solidly fixed, so it is not this moving, it definately is the plug wobbling in the socket.

Looking at the plug, there is a sprung ring on the connector to hold it in the socket, the play seems to come from the barrel of the plug moving within this ring (that itself has locked into the socket). I am not sure if there is a problem, as this may just be normal for this type of plug, but it seems odd.

Does anyone have an external antenna using a MMCX connector? Can the plug easily be wobbled when in the socket?
