This is the link missing from my original email , the other was for the 1.125

the specs are close or similar to the 1/2 CATV, but this is more flexible

There's a 75 ohm version of Times Wire LMR 600? I've never seen an
other than 50 ohm and I believe they'd have to change the name for a 75
ohm version.
He made the remark "I know the LMR 600 is 75ohm so there will be a bit
of a mismatch" which is not true.
I wonder if there isn't just a misconception here?
I have over 1500 feet of the stuff and it's all 50 ohms
Although I use the UHF connectors as well, all the ones I've seen for
LMR-66 are quite fragile to leverage, so the coax needs to come straight
away from the connector. I've broken several by having them at the end
of a loop.
