Re: Updated SG504 Head 2 Head comparison

 

Some OEMs use 50 ohm BNC connectors for video, because they are harder to damage. Look at the photos of the two types and you will see the differences.

To this day I do not believe you can buy a true 50 ohm BNC connector. They are more like 51 or 52
ohms.
It is even worse with 75 ohm BNCs. I've tested several chassis sockets on the market using TDR
(7S12/S52/S6) and there are significant reflections within the connector body. Must try the same with
50 ohm ones.
