I worked on radar systems in the late 60's. We were always told to assume a 3db 
loss for any connector inserted into a test line.

It's an adapter, not a stub. There's no cable involved here, just a turned metal 
interface. My biggest concern is that the small connector into the back of the 
USB dongle will be the one that falls out when I push the server back into the 
cupboard. Fortunately, not happened yet.
