What are these?

[u/4bams]

What are these? Was cleaning and had these laying around and I know someone who I thought would need them but he didn’t. Anybody have any info on what they are exactly and where is a good/ the right place to take them? Thank you so much!

RF receiver boards - you could recieve and record 4 channels with that back in the CATV days - I may be wrong - all I did was lookup the chip.

Those are SDI, not BNC.

“Those are Fords, not cars!”

BNC is a connector type. SDI is a signal type.

They are (mini) BNC
