50 ohm BNCs (RF impedance) certainly exist.

Except that (I thought) coax for TV is 75 ohms

It is so get 75ohm BNCs. They exist and in right angle formats.
Baseband video is 75ohm.

But your UHF radio mics use 50 ohm. ;-) Think if you look at the spec, 75
ohm BNCs aren't suitable for HF.

And BNCs are overkill for a TV aerial socket which rarely gets unplugged.
