Mike,
I bought some from this Link
<https://www.ebay.com/itm/30m-RG179-RF-Coaxial-Cable-Connector-75ohm-M17-94-RG-179-Coax-Pigtail-98ft-AT2/372820060893?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649>
.
It seems ok to me.
No markings on it and the guy could use a lesson on how to coil wire.
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.
I scanned it from 100khz to 10mhz ... SWR was 1:00 to 1:35... and on a
50 ohm dummy it was 1:12 to 1:35.
Not really sure if that tells anything but there it is.
I have nothing to measure L or C.
I did try shorting one end of the coax then scanned it with the 230 zoom
read L and C and then calculate the impedance but didn't look right.
Bad math on my part I'm sure.
I also bought these connectors and the worked just fine...Link

I have made four on these chokes now all test the same.
I have one in service and waiting for the rain to stop to install the
other ones.
I am replacing old chokes that work but take up to much room...I'm sure
I will see no change when I do this.
The old chokes were made from old Commscope RG 59 with 4" cores..works
but too big...
Also I can send you a piece if you want to see it or..... better yet how
much do you need?
I think I used 5.5 feet for each choke.
