Hi All,
I would like to warn everyone. Avoid adapter with the rounded end of the centre pin. You may damage the antenna socket on your SUNSDRxxx
Check before buying or using Mini UHF to SO239 adapter.
I have purchased Mini UHF to SO239 adapter from Martyn Lynch distributor in the UK as at the time pigtail cable was not available.
I have received two pieces of the adapters one with the brass centre pin (sharp end ) and one adapter with the nickel finish round end as on the photo below.

The round end adapter damaged my antenna socket as you can see on the attached video.
It is very hard to remove the adapter from the antenna socket, as the centre pin sits to tight and after removing it you can clearly see that the socket is damaged.

Typical Chines crap connectors All Chines are very shiny and waste of money,

You are absolutely right,
But now I'm stuck with this problem as Martin Lynch dealer don't care.
Manufacture doesn't have to, as warranty clearly say that the mechanical faults are not covered.
The only positive is I'm able to do it on my own, I just need the part.
