Jim,
That's what I thought.
Can you figure out impedance of coax with a device like the Rig Expert?
Also I was only sending the info to somewhat confirm it's 75 ohm cable
because it's not marked.
I was not saying that it's a good or effective choke because the SWR was
good.
Thank You

I put 75 resistor and 50 ohm dummy load on each choke and scanned it
with the Rig Expert 230 zoom and it seems fine.
Common mode chokes do not affect SWR, and measuring SWR tells nothing
about their effectiveness. See http://k9yc.com/2018Cookbook.pdf
