The Liberty connector was supposed to be for Belden 1505F, but installing the cable into the fitting I could never push it in as far as the viewing slot. The fit was so tight it pushed back the outer jacket back .My hands were sore as heck from pushing twisting pushing twisting etc.
The other problem was the inner braid was missing that ity bity hole. By removing the compression ring, and slidding it up the cable, I was able to push the cable in ( to the viewing slot )and test , if it was good, slide the compression ring back onto the RCA plug and compress it.If it wasn't , remove the cable and start over.
( When it didn't work the inner braid was balled up.)
