usb dongle

I am thinking of getting a ADS-B dongle. Can anyone tell me what size the bayonet connector that the SBS Basestation-1 uses as I will need a conversion connector to use my external antenna.

Thanks in advance,

Bob.

What model SBS?

If it's an SBS-1 it has a BNC connector.

Most USB dongles have an SMA connector.  Note it's SMA not RP-SMA:

But some have MCX.

Thank you for the info. Will now see if I can get that type of adaptor.
