I received this flat cable.
I had to order something from Amazon anyway and I found this pretty cheap so I tried it. Well; now I know my previous flat coax is rubbish; well at least even more rubbish.
Range has improved somewhat; I can reach England! And part of Luxembourg! And now entire Belgium instead of only partially. And more of Germany.
That was a good buy. 
Tomorrow during the day I will use the F-F adapter to see what the results are withouth the flat coax. Just so I know what the setup is capable of.
I can’t wait for FA to get stock on the FA stick on Amazon.de again.
Curiously I got this error on my laptop. Feeding FA/FR24/Planefinder went fine though…

But changing adress from IP-adress/dump1090-fa/ fixed that…
