One antenna slightly loose on rear of A6

As per the title, one of the antenna's feels a little loose on my week old unit....Is there an easy way to tighten it?

 

Does it tighten if you turn its it clockwise...?

 

Yes, I simply used a 8mm open ended spanner to tighten one of mine.

 

Thanks for the replies both....Tbh my unit is just sitting on the hifi rack at the moment and I noticed how loose one of the antenna's was last night.
First thing I thought of was how to avoid marking the shiny finish with a spanner!

 

Those antennaes are meant to be removable, so it may just be not tighten enough... you could try by hand; it doesn't need to be soooo tight.
