There is no problem to run the LMR-600 , if you are sure you have the 75 ohms version
you can "adjust" for 50 ohms for 6m, I did that for the 1/2 CATV who feed my
1/2 vertical for years before the change to 1/2 hard line to be used with the beacon
the matching section is easy to make for 6m, you can find it online or the
antenna book
the LMR 600 need to say on the jacket LMR-600-75 if not can be the 50 ohms

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.

I have about 100ft of new LMR600 and also two new UHF connectors to fit the
line. I am Feeding a three element 6M yagi through 50ft of RG213....the end
of which is about 8 ft up the side of my HG52SS tower.....What do you think of
an idea I have to use the LMR600 to feed the end of the RG213 and run directly
into the shack for the K3 for 6M use. I know the LMR 600 is 75ohm so there
will be a bit of a mismatch ...will it be significant?...as far as the K3 is
concerned?
