GL-AR150 External antenna mount missing nut

Is it normal for the external antenna mount to be missing the nut? It makes for a very unstable mount of the antenna on my GL-AR150 I just received.

There should be a nut. Can you show a photo?

Oh, ok, I didn’t get a nut, so mine is all loose.

Hi Markus,

Sorry for this. Can you give us your address so that we send you the nut?

Oh, no problem, thank you. I have sent you an e-mail to service (at) with my address.
