Which part is missing

Hi all!

I ordered a few parts a short time ago

1x IPAX/U.FL to ReSMA Chassis Socket - 15cm
1x 18V 1A UK Power Supply
1x Omni Antenna 2.4 GHz -5dB
1x R52 802.11a/b/g Mini PCI
1x RB333 Indoor Case
1x Router Board 333

I’m not sure if there is any part i forgot to order as when I screw the antenna on the antenna cable, it is not holding on the indoor case. It seems that the 3 holes at the back of the case are bigger then the golden screw part of the cable and therefore the cable and the antenna are always faling off the chassi

Please let me know if there is any part to order so I can mount the antenna to the chassi

Best regards,
Christoph

RB333 indoor case designed use with N-female Bulkhead pigtail or AC/SWI Swivel antenna.
